This is caused by the date settings in each of those report elements.

By default they use "last month comparison date range prev period".

The problem is until the new data of the prev month hasn't been published yet the report tries to compare e.g. Jan 2021 to Dec 2020 - but on Feb 7 the Jan data is not  available yet.

The only workaround I found for this is to have a copy of the report and change the element setting to 

custom -> advanced - > start date: today - 2 months end date: today - 1 month

Do this for all the elements which have the "no data" problem.

A bit of a hassle and I haven't figured out yet whether it is possible to embed such logic in one report.
