Problem with Admin columns

I use “WP Admin Columns” quite often, which is a common plugin.
Then I suddendly could not use “bulk edit” from WordPress anymore. I contacted the WP Admin columns support, and they found a bug from “Post Expirator”. This is their message (and solved the problem). Would be great if you can only validate the field if existing.

Support Mail:
—
`I see that the plugin ‘Post Expirator’ is preventing the bulk edit modal to be saved.
The reason is that the bulk edit field ‘Expiration’ is not in the form.
Since the bulk edit field are often only available when the column is added, this field was missing because the column was not added.
Once I had added the ‘Verf?llt’ column again to the page, the form was validated and posted correctly.

This is a bug/issue that needs to be solved in the Post Expirator plugin. They should not validate the bulk edit form when their column/field is not available.
Our plugin makes it possible to remove that column and thus the field in bulk edit, which will trigger the issue.
For now, re-adding the column will fix the issue for you.`
