@d-healey said in [bug] Pasting samples into group not working:

In the sample mapping window, no matter which group I have selected pasted samples always go to group 1.

If you copy/paste your samples, they are indeed pasted in the 1st group but after pasting them, if you immediately click on the RRgroup + or - buttons at the bottom of the sample map, it moves the samples to the desired group. Even if they are not selected you can still move them...
(Hoping you don't have too many groups...)

Edit : tested on macOS, commit from Jul 25 :)
