Rotoscope V3 not learning properl

Using AE V24.1.0 Build 59 on Windows 10 as seen from the attached images, when rotoscoping this subject, the AI algorithm keep including the chest area approx every 5 seconds.  If I let this proceed unchecked, Roto V3 eventually includes the complete chest area.  So every 5 seconds I had to keep telling AE Roto V3 to include the chest area and the algorithm just never learned to keep it excluded.  Maybe we need a mask to tell Roto leave this area alone?
