The Rfam annotations are not consistently shown for the different RNAcentral IDs.
For exemple the URS0000904F64 has an RFAM annotated family
https://rnacentral.org/rna/URS0000904F64/9606
But it is not present in the rnacentral_rfam_annotations.csv
And there is nothing in the Rfam classification section of the webpage either.
