I also have this issue with CPT-onomies, but I don’t have that Toolset Types plugin. This seems to be a bug in CPT-onomies js code.
First of all, it’s not a new issue. See this issue from a year ago, and this one from 9 years ago. Notice that neither have a reply from the plugin author, so expect this issue not to be solved ever.
Second, the issue is caused by bad, ugly, convoluted unnecessary javascript. The issue is in assets/js/admin-edit.min.js, where the author overrides the default WordPress code to save the quick-edit form, to add some sort of weird checks to the column values. That code is all over the place and simply bad: it loops through all the css classes of each column to figure out the names of the columns (when he could simply get them from the th ids at the top of the table), which causes fake values (for example: the code thinks “column-primary” is a displayed column, when it isn’t). Then, it loops again to figure out if a column is or not to be updated. But it starts at index 1 when it should at index 0. After that it makes multiple ajax requests to get the column values….anyway, I can’t find any reason for this code, other than maybe the author was on drugs? not sure.
Long store short, it seems all that code that creates this issue doesn’t need to be there. The fix is to ignore it.
You probably can edit the file in the plugin folder cpt-onomies/assets/js/admin-edit.min.js. It’s a minified file so hard to edit, but look for the code $wp_inline_edit_save.apply(this,arguments);
and add
return;
after that. That makes it ignore the rest of the code. So far, it seems to be working ok for me.
