Charge conjugated decay descriptors creating duplicated parents

I noticed some combiners which has decay descriptors on the form of: [B0 -> J/psi(1S) KS0]cc. This will duplicate the B0 candidate with the same daughters and to me has no purpose in the end. It's just saving all the B info twice, I would suggest to remove the cc in all these cases. I found 30 cases, mainly in RD. Attached is a JSON dict with the combiners and lines. Could we notify the authors of these lines @mramospe?

duplicate_combiners.json

Also @mvesteri, is this something we should flag in the future?

Update: There is a check for this in the ParticleCombiner code but the warning never shows up anywhere? I printed the names of all the combiners that trigger it, there was 105 cases on master:
