Lumetri color Bug: when making changes suddenly go back to previous state.

When editing color using lumetri, suddenly if i go to other panel, like timeline, the changes go back to where i starterd, if i made changes, save file, close proyect and reopen, changes are saved. But, if i make some change on the sliders of lumetri, even on curves, and change panel. sometines reset to those values. 

it make me mad, cause is erratic.... 

it begun on a proyect made on 24, upgraded to 25, but algo on new proyects as well. 

i flushed media chache... but still not work.
