Cant get acces to morph targets

Found another video with UI slider making and with making some blueprints- looks easier then yours - but that approach also didnt works… it;s looks like my morphs just do not works… at all .
Maybe there is some restrictions in naming … i do not know… or maybe this is unreal bug in current project or unreal version (tried another project it still doesnt works) i made slider to control morph … all UI works well but nothing changes:

looks like changing VALUE in “set morphs value” node didnt change anytthing, no mater how to call this value changing…
