Weird frame numbers in Silhouette Paint in After Effects

I have a clip in AE using Silhouette Paint and I’m not able to set a custom frame range for Auto Paint because of the weird frame numbers (screenshot attached). The working frame range says 222 to 268, but the numbers listed in the Custom range are wacky, and if I try to enter a value like frame 230, etc into the custom range values, as soon as I hit ‘enter’ or click outside of the boxes, the custom value jumps back to the weird numbers. Am I doing something wrong? Thanks for any help!

Before entering the Silhouette Paint user interface, can you make sure you set the time display to frames in After Effects. If it is set to timecode, Ctrl-click to change it to frames.

Does this solve the problem?
