cannot find my installed extension

ı installed 3d slicer 4.10.2 after setup two extension t2 mapping and segment editor extra effect. I use windows 10 64 bit. but ı cant see this extention in module list. can you help me?

SegmentEditorExtraEffects extension adds new effects to Segment Editor module (does not add new modules).

T2 mapping module should show up in Quantification category.
