That document seems to be dealt with quite well, except it's a bit of a difficult one in that the number of columns isn't stable. Just setting it to three seems fine though, also where there are only two columns.
Were you by any chance using a nightly instead of the stable? There's a reason the GH bug report template asks for that kind of information.
Because if so you need the 2020.04.1 release to prevent some minor cache mismatch issues that were present for a couple of weeks.
