Muting a track does not mute vst

ive used renoise version 3.4.2 for a very long time, but recently updated to 3.5.3
now when i revisit some of my older songs ive noticed that when theres a muted track thats been muted using the sequence matrix, it no longer stops the VST from making sound
is there anyway to fix this?

Which setting are you using for: [ Options → Mute Mode ] ?

off, but i set it to mute and it doesnt change anything. dont think its related to my problem since the track thats been muted by the sequence matrix says “PLAY” on top like all the other tracks

Just a work-around, ive never tried using the ‘sequence matrix’ for anything, but entering L00 in the effects column should lower the volume of the track and mute the sound, later entering LC0 will raise the volume back up.
