Compared periods with goals always shows 0

Using 3.14.1 (and previously 3.13.5) any standard report that shows goal conversion activity always shows 0 for conversion counts and percentages when using the comparison feature. The feature works when applying it to a custom report, but any view that shows goal metrics on a standard report doesn’t. Does anyone else experience this? I checked the Matomo demo site, but it’s running the 4.0 beta now so don’t have any other point of comparison.
