Remove a user from a segment that they were imported into

Your software
My Mautic version is: 4.2.1
My PHP version is: 7.4.28
My Database type and version is: MariaDB 10

Your problem
My problem is:
I have some segments where users were imported via CSV to the segment.
How do I remove them from that segment?

These errors are showing in the log:

Steps I have tried to fix the problem:

Nothing on the Contact page (that I have found) allows this.
Suggestion would be to add a functionality like campaigns where users could be manually added or removed from a segment with a toggle switch.

If they were imported into a static segment then you would need to either view the segment, mark the ones that you want to remove and at the top drop down of the checkbox you can then choose “Change Segment” and remove them from a segment - not ideal as the maximum you can do is 100 at a time.

The other way is to use some logic inside campaign to do this for you as well. All depends how things are setup I guess
