The paragraph has options rvpaoReadOnly, rvpaoDoNotWantReturns and all items of its have protection rvprConcateProtect, rvprModifyProtect, rvprDoNotAutoSwitch, rvprSticking, rvprDeleteProtect, rvprParaStartProtect.
But actions like TrvActionParaBullets, TrvActionParaNumbering and TrvActionParaList are available for it.
I confirm the problem.
Lists operations must respect rvpaoReadOnly, sticking options, as well as a delete protection of the list marker.
It will be fixed in the next update.
A fixed version is uploaded (for registered users)
1) The problem with paragraph lists and protection is solved.
2) I was wrong when I said that there was no option for protection of paragraph style. There is rvpaoStyleProtect in Options of paragraph style. But TRVRuler ignored this option. Fixed.
