Problem report for Slicer 5.6.2 win-amd64: HI Everyone! I am experiencing some problems with DrawTube function. The fiducials placement key is always disabled. (gray), therefore no fiducials can be placed to draw the tube. Both _SegmentEditorEXtraEffects_ and _MarkupsToModels_ extension are installed.  
Slicer Version is 5.6.2.

Any suggestion?

Thanks a lot in advance!

Short addition, maybe helps: I have just noticed that also in the function Surface cut the fiducial placement key is disabled.
