Errors retreiving L1:GDS-CALIB_STRAIN from the frame backend. Must ask for CALIB_STRAIN_CLEAN and CALIB_STRAIN_NOLINES as well

When querying arfw1 which hosts an instance of the arrakis server running with the frame backend server I am unable to request just L1:GDS-CALIB_STRAIN, but must also request L1:GDS-CALIB_STRAIN_CLEAN and L1:GDS-CALIB_STRAIN_NOLINES.

Interestingly enough I can query the STRAIN_CLEAN and the STRAIN_NOLINES individually and it works.

I get a key error KeyError: 'L1:GDS-CALIB_STRAIN_CLEAN'
