Captivate Classic simulation recording no longer custom size for application area

We have a custom size we record software simulations in, 1728 by 1080 (for reasons). Ever since I downloaded the latest version of Classic 11.8.3.8 I am not able to record the application area at that size. It used to be the application would snap to the size but no more. The only work around is to record a custom region and manually size the app to that size which is not ideal. Is this a known bug?  Or does anyone have a solution? Thanks in advance!
