Retargeting RTG and Scale Problem

i think the hand and the socket under it shrinks it’s scale whenever i play animation retargeted by RTG with newer version

and when i play animation with older version RTG, no shrinking,
anyone know this ploblem?

i retarget animation between full body and edited body that is only arms for first person animation and if i use older retargeted animation it works fine
feels like it is bug
