Cannot Move Volume Automation Marker

I cannot select or move volume automation markers that were previously created. I can create new ones but then those get locked and cant select them to move them later. Any assistance greatly appreciated.

I think I FINALLY figured it out. For some reason Cubase was placing extra markers on the same position so when I select the marker it actually selects markers under it and doesn’t select the top one so appears not to select marker in that location.
