MIB2 "Current version" problem

[GuBob]

Hi everyone
Looking on the forum I’ve red a lot of topics where is possible to update the MIB by ourself.
I decided to update because during calls, via Apple CarPlay, sometimes the voice of the interlocutor start crackle and the Infotainment stop working
Yesterday i had a look on my MIB to know which version is installed on.
The strange thing is on the “Current Version”
Instead of the current version of my MIB there is nothing. You can see in the image that I’ve attached.
That’s normal?
Should I’ve update it?
is there a detailed guide to update the MIB avoiding to broke it?

Thank you so much in advice for the help
