Smooth button in Variable Layer Height is broken

After the recent version updates, I noticed that the “Smooth” button in variable layer height function is broken. After I use Adaptive to automatically determines the layer heights and clicking smooth, then it just reverts to constant layer height.

After clicking adaptive:

After clicking smooth:

Tried the same on multiple models, some of them works fine, some of them doesn’t. Is this a known issue?

I get this also, SOMETIMES it smooths but I can’t find a reason as to when, in the same 3mf on different plates I have two objects, it works for one, not the other with the same settings. I can still try and manually smooth the graph but its a pain…

after some playing with same issue, i think i found out the reason, whenever Raft is enabled, it disable the Smooth button.

I have the same issue. It also resets when I touch the zero value. Do I have to make a raft in the model then?

I tried to modify the layer height and then set raft. That works.
