Suppose a preset has 2 pages, page 1 visible. When changing the name of a group on page 2 by sending a LUA function like ‘local group = groups.get(21)# group:setLabel(“B-Return”)"’, this ALSO overwrites the group name shown on page 1 at the same visible location. But only temporarily: when switching to page 2 and then back to page 1 the true group name is shown again.
P.S. Exactly the same happens with control:setName()
