Average Annual Return

I just transferred by files from Quicken 2016 to Quicken 2019. I have one mutual fund with Vanguard that changed from the standard fund to the Admiral fund in 2018. The change was registered as removal of the old shares and then adding new shares with costs and date acquired. Quicken 2016 showed correct 1,3 and 5 year average annual returns, but in 2019 shows the same return for all three instances.
