Cant delete tables

Hi

Nice product but it does not work properly.

As you can see I created this table https://www.commissionit.co.uk/art-commission-opportunities

The problem is when you click delete table it does not delete. Seems to be conflicting with previous data.

I’ve even tried uninstalling the plugin, deleting it then re installing but when you do all the tables and data are also still there…

Probably a simple fix to do with it not being updated to the latest wp version?

Thanks
