Help with FMLA

I work at Kaiser and need to go on family leave to provide care for my wife. In the paperwork that I filled out, the physician filled out her portion and it was sent in and approved. She has both Kaiser and Sutter, Kaiser is asking for a note from her physician to be uploaded on her medical record, but the doctor we went through was not Kaiser it was Sutter. Kaiser is also asking me now to call and file with the EDD and are garnishing PTO hours versus the state paying me - I’ve been getting a huge run around between Kaiser, the state, HR, EDD etc. has anyone gone through anything similar?
