I tried what you described but did not face any issues. The Assign button worked fine when trying to reassign new unit names.

Either way if you can replicate it and you believe you have found a bug the best thing to do is email us at support@ since this is a community forum. Thank you for your understanding.

I've had that as well. It turns out that you have to put your cursor anywhere else then the field you filled out. Then the button becomes clickable. This does not happen always. It also sometimes occurs with Transform (the function I still think should be called Translate). I must admit that I did not yet see it happen with 2023, only in Capturee 2022.

This was resolved by Capture Support.

I had failed to enter a 1 in the Overlap field.
