Attached it is a spreadsheet with the problems from my data set.

I see no blocking. For example, the list shows From: bayer.com, d=crm.bayer.com, the latter deemed blocking. Both domains feature a DMARC record and (unsurprisingly) none has a psd= tag.

According to the spec, one should look up:
_dmarc.bayer.com
_dmarc.com

And then
_dmarc.crm.bayer.com
_dmarc.bayer.com
_dmarc.com

The organizational domain is bayer.com and they are aligned.  No blocking.

Best
