Sim08a and Sim08b database tags are not found with bk_query

There are 3 samples for which the database tags are not being found in the current test job for Lb2Lll: https://gitlab.cern.ch/lhcb-datapkg/AnalysisProductions/-/jobs/10761977

For example for 2012_MagUp_Bd2Ksmm, the path is evt+std://MC/2012/11114101/Beam4000GeV-2012-MagUp-Nu2.5-Pythia8/Sim08a/Digi13/Trig0x409f0045/Reco14a/Stripping20NoPrescalingFlagged/ALLSTREAMS.DST

The relevant tags (from my own bk_query) are 'Sim08-20130503-1', 'Sim08-20130503-1-vc-mu100'

The samples are still available in the bkk; what I did not is that these are the oldest samples in our analysis, being from Sim08a or Sim08b. Is it possible that these samples are too old to work with the current AP settings?
