When I launch the interactive table modal, click add table, and then actually input the table information the table is not created.
I tested in Chrome (with a clean cache and no addons) and Firefox, issue replicates.
I performed a hard refresh, issue replicates.
I ran a console query and found 7 errors, but these two appeared when the "shift+enter to create table" button/keyinput was provided:

Issue also replicates if you select no folder.
Creating a new interactive table.
Update to this! I figured it out, tables still can be created but the name of the table needs to be more than three characters long. I was making a table of teas for my campaign and thus the table was just called "Tea". If I named the table "not tea" it actually created, so that was probably the issue. Still, a note or something that table names need to be longer than 3 letters would be helpful.
