This topic was asked before by someone with a video that exactly explains my situation.
It never got an answer on her [last time]
Fusion is a mess. It's only the fusion page. I have updated to the latest version of DaVinci and I have reset UI... I have tried everything I can think of.
On a search I found the thread on here by someone with the exact same issue [though they had it when 17 was in Beta] they posted a video and it shows/explains exactly my issue.
I have the studio version, I am on Windows 10.
If anyone has a solution that would be amazing as I am at the end of a project and want to finish it off and post the film... argh... thanks for any help
