Version 1.02 and "No Update available"

I have 2 PS4
Since 2015 I have BHC labeled with CUSA-01446. Actual with Version 1.04

Yesterday I bought at German “Media Markt” second BHC. This was labeled with CUSA-02980. I want to play COOP with 2 PS4 systems. But with second BHC PS4 only downloaded update version 1.02 and displays “No Update available”

How can I bring PS4 to update this version to Version 1.04?

Same situation with both PS4. Both discs create Different symbols in PS4 menu. One updates on both PS4 to 1.04 the other (new) one only to 1.02.
