Giant tcr 2019 BB, 2 different sizes?

Hi,
My giant tcr has 2 different sized bearings in the bottom bracket.
2841/44 LLB and 3041/44 LLB
It also looks like just press fitted steel bearings, no plastic tube joining them.
Has anyone replaced this?
Its noisy and needs replaced.

Thanks

What model TCR, which crankset and is it the O.E. factory original?
