Brave Rewards withdraw problem

Hey, I have an issue with Brave/UpHold
I have 55 BAT and wanted to withdraw them to my uphold, so I linked them but for a reason I don’t know, I can’t withdraw funds from brave to uphold (no button) but Brave sent me ~17 Bat to my UpHold, so my Uphold now have 17 Bat, and brave rewards tells me that I have 71.250 Bat but still can’t withdraw them. I pressed “Disconnect from Brave primes” (something like that, I have it in french, sorry) and the 17 Bat are gone and still can’t withdraw, the 17 bat comes back when I link Uphold again, so my question is, how can I withdraw the 55 Bat I had initially to uphold ?
