Blacklist and showlast commands not working

The command /inventorysorter showlast always shows inventorysorter:dummyplayerinventory no matter what kind of chest is opened.

and command /inventorysorter bladd is not accepting any argument.

I even attempted to manually add blacklist to the config file, but the blacklist is not applied.

Could you let me know what version of MC this was effecting?

Sorry this was a couple years back, I don't recall.

No problem, that's for getting back to me regardless, hopefully this has been resolved with the latest versions I've pushed out 👍
