Version 4.26.1 - can't add custom curve in timeline node

i’m using version 4.26.1, the lastest version

after I create a custom curve in the content browser, I can’t add this curve in my blueprint timeline node

I also tried vector and float curve, same problem

to be sure, I’ve tried this on version 4.15, it works fine


one user said this still works fine in 4.25,
