Editing Volta's no longer possible in musescore 3.2.3

Hi there,

In musescore 2.x.x it was possible to edit the voltas, with volta properties. But I can't edit the voltas anymore in the newer musescore versions.
So for example I want an ending with a prima volta and a second volta in one bar.
Like 1,2. And then 3,4. and maybe 5.
In the older version this was possible, but no longer in the newer versions (my version is 3.2.3)
I hope this can be fixed in newer versions.
Or if someone knows a way how to do it, please let me know.

Thanks,
