Problem with linking parents file as dependent

Hi there,

I have a problem with linking parents file… if they qualify for the WITB and provincial credit, by link both their file to their daughter for purpose of caregiver claim, the WITB and provincial credit will appear on both return after linking. Can someone suggest how I can fix this beside detaching the file? Also, I think the linking feature need some improvement, because when link a parents file who are married, I need to detach them first then link it to their daughter file… or am I missing something here?

Thanks a lot
