Subtract step disagrees on frequency label with DDF

I am running the full delay-calibration workflow with lotss_subtract on a full dataset with toil and slurm submissions. During the sub_sources_outside_regions.py script I got an error for two of the concatted SBs. It seems they tried to access 127Mhz and 129MHz which are not present in the DDF/SOLSDIR. In there, I have 126MHz, 128MHzand130MHz`.

I'm not exactly sure where this mismatch arises or a fix but I thought I should note it as an issue for the time being.
