Timeline time warp frame handles

hey all, i swear this used to work. i have a clip in my timeline with a 400% tw on it . it is showing 2 frames of handles . i want to hard commit the shot and include the handles before i export. when i try and trim the 2 frames out the number of head frame goes up ? if i have a clip without a time warp i can trim the head and tail frames to zero every time ? am i missing something ?

Is the trim mode set to Proportional?

is that a preference ? i tried the same procedure in 2024 and it works fine ?

i found it ! eesh . i needed to switch to shift !

Or pin. TW is unique in that both modes work the same.
