Adour keep putting zynaddsubfx vst to blacklist

Windows log:
[INFO]: VST Blacklist:
C:\Users\Lukas\Documents\Plugins\VST\ZynAddSubFX.dll

I downloaded the plugin on the offical site: http://www.kvraudio.com/forum/viewtopic.php?t=268277

Whenever I clear the blacklist Ardour will automatically put them back in again

So Update:

it turns out Ardour blacklist zynaddsubfx is because the vst version is only available as 32 bit and I’m using 64bit version of Ardour.

I will attempt to reverse back to 32bit of Ardour
