I believe this problem has since been fixed!

As far as I remember, the issue is that your version of matplotlib is probably higher than 2.2.
So the 2 solutions are to downgrade back to MPL 2.2, or to download the nightly (less stable) version of Mantid in the bottom right here.

Whichever you try, tell me how it goes!

Indeed:

matplotlib.version
‘3.3.0’

Downgrading matplotlib? No way…
The night built works nicely concerning that problem of mslice interface.
Thanks for the help.
