Vegas Pro 23, Build 352 in Bezier masking selecting "curve" greys out all options. Steps to reproduce: On any video add a Bezier mask. Click on the arrowhead beside Mask 1. Selecting "oval" "rectangle" or "diamond", no problem. Selecting 'curve" results in all options being greyed out, at this point options are also greyed out in Mask 2. There used to be an option to place points and draw out a mask, all that is missing.
