Clef changes in Divisi Staves

So, for string piece I was working on, the cellos divide for a few measures, but the 1st division goes quite high, so it is logical to have those read tenor clef, the issue is, in page view, changing to tenor clef makes BOTH staves read tenor clef. The 2nd division does not need tenor clef and I would prefer it does not have tenor clef. How do I make the tenor cleff only apply to the top division?

Provided you’re changing the clef in an actual divisi section rather than in a part of the staff where the music is actually unison but displayed on multiple staves, then the clef will change only on the divisi staff on which you create it. If you’re finding this not to be the case, please attach the project so we can take a look.
