Looks like there's some JS code missing after disabling the Overlay plugin. See:
Uncaught ReferenceError: DataTable_RowActions_Overlay is not defined
It's a regression because it worked in 2.15.0.
That already seems to be fixed in master. Can't reproduce that on my local instance.
Thank you for creating the issue. It was fixed as part of this issue: https://github.com/piwik/piwik/issues/9704
