Devialet expert pro sweet room beginner's guide

[G51]

Finally have grown up to it and also concluded I need to implement some equalization as my room is far from perfect (especially in bass region) .
I thought would try sweet room first and if not successful then as my last part of rescue something from minidsp with dirac.

BUT and big BUT had a look at the devialet info about the SWEET ROOM read all and not really sure or convinced how to use it.

Can you please help me with it.??
I have measured the room initially with REW and found some dips but also PEAKS around 30 to 60 Hz which for me is more important.
Generally that peak makes some songs very unlistenable in my room even with using the bass correction on maximum -18db

The speakers I am using at the moment are some Kef reference 1.

Please help!

I have attempted my first correction of sweet room eq but without success.

Every time I got the bad file message once loaded onto my amp.
