[Modding] issues with attaching particles

I was working on my mod, where I am attaching the p_onFire particle to an enemy via a buff.

Seems like after about 1 second (when buff update is triggered?) it will auto remove that particle.

When switching "p_onFire" with "p_electric_shock", the shocking particle lasts the whole duration of the buff, but is not being removed the the buff is removed.

Code example:

Buffs.xml

<configs>
	<append xpath="/buffs">
		<buff name="buffScorchTest" name_key="buffScorchName" description_key="buffScorchDesc" showonhud="true" icon="ui_game_symbol_near_death_trauma" icon_color="255,0,0">
			<stack_type value="replace"/>
			<duration value="0"/>
			<display_value value="varScorchDuration"/>
			<display_value_format value="time"/>
			<effect_group>
				<!-- Duration Handling -->
				<triggered_effect trigger="onSelfBuffStart" action="ModifyCVar" cvar="varScorchDuration" operation="set" value="3"/>
				<triggered_effect trigger="onSelfBuffUpdate" action="ModifyCVar" cvar="varScorchDuration" operation="add" value="-1"/>
				
				<!-- Particle & FX -->
				<!-- SWAP TEST: "p_onFire" with "p_electric_shock" also "p_impact_metal_on_organic" -->
				<triggered_effect trigger="onSelfBuffStart" action="AttachParticleEffectToEntity" particle="p_onFire" parent_transform="Spine1" local_offset="0,-.2,0"/>
				<triggered_effect trigger="onSelfEnteredGame" action="AttachParticleEffectToEntity" particle="p_onFire" parent_transform="Spine1" local_offset="0,-.2,0"/>

				<triggered_effect trigger="onSelfDied" action="RemoveParticleEffectFromEntity" particle="p_onFire"/>

				<triggered_effect trigger="onSelfBuffFinish" action="RemoveParticleEffectFromEntity" particle="p_onFire"/>
				<triggered_effect trigger="onSelfBuffRemove" action="RemoveParticleEffectFromEntity" particle="p_onFire"/>
				<triggered_effect trigger="onSelfLeaveGame" action="RemoveParticleEffectFromEntity" particle="p_onFire"/>
				
				<!-- Effect of being Scorched -->
				<!-- <passive_effect name="HealthChangeOT" operation="base_subtract" value="5"> -->
				<triggered_effect trigger="onSelfBuffUpdate" action="ModifyStats" stat="Health" operation="add" value="-5"/>
				
				
				<!-- Cleanup Handling :: Scorch -->
				<triggered_effect trigger="onSelfBuffUpdate" action="RemoveBuff" buff="buffScorch">
					<requirement name="CVarCompare" cvar="varScorchDuration" operation="LTE" value="0"/>
				</triggered_effect>
				<triggered_effect trigger="onSelfBuffRemove" action="ModifyCVar" cvar="varScorchDuration" operation="set" value="0"/>
			</effect_group>
		</buff>
	</append>
</configs>

And for a way to trigger the custom buff:

items.xml

<configs>
	<append xpath="/items/item[@name='meleeWpnBladeT0BoneKnife']">
		<effect_group>
			<triggered_effect trigger="onSelfAttackedOther" action="AddBuff" target="other" buff="buffScorchTest"/>
			<triggered_effect trigger="onSelfEquipStart" action="AddBuff" buff="buffScorch"/>
		</effect_group>
	</append>
</configs>
