Unable to remove freenas-proxmox

So while attempting to install this plugin to my two Proxmox nodes using the provided method (apt install freenas-proxmox), I misunderstood my browser caching the PVE web interface causing the FreeNAS-API option to not show up in the dropdown as the install failing. In the confusion I followed another older guide which involves patching PVE files manually (guide) which after some retrospection is a VERY bad idea.

Now one of my proxmox machine is incapable of uninstalling freenas-proxmox or reinstalling it because the post-uninstall script keeps failing with the following logs

Errors were encountered while processing:
 freenas-proxmox
Processing was halted because there were too many errors.

While another one of my node doesn't seem to suffer that fatal of an error and can add the ZFS over iSCSI storage, but attempting to migrate my existing VM disks to the storage, it always errors out with the following logs

Warning: volblocksize (4096) is less than the default minimum block size (16384).
To reduce wasted space a volblocksize of 16384 is recommended.
TASK ERROR: storage migration failed: freenas: unknown iscsi provider. Available [comstar, istgt, iet, LIO] at /usr/share/perl5/PVE/Storage/ZFSPlugin.pm line 35.

Any assistance is appreciated. Thank you
