Rearranging Columns Issue

Hi all,

I am trying to rearrange columns in my question and had no problems doing so but I just added another column and it is now permanently locked at the bottom and I can't rearrange it.

There doesn't seem to be anything erroneous about this column compared to my other ones so I am wondering if this is a bug so if anyone has any helpful info I would greatly appreciate it!

please post diagnostic info an a screenshot of the problem
