Mix flgpbk03 and flgpbk04

Hello,
in my tank is the last flgpbk03 an now i got new flgpbk04. Can i just put den v4 Cadrige in and ignore the messages, so it will be mixed up in tank or are the v3 and v4 not compatible to mix?

Thanks,
Mario

For resin compatibility.

I have done that with both grey and black and did not have a problem.
