Mosaicing tool changes radiometric scale

After using SNAP Mosaic tool to extract an area of interest in between two overlapping granules, all bands were converted to float32 with values between 0 and 1.
Is this an expected behaviour ?

did you chose any other outut format than Beam DIMAP?

That they are afterwards float32 is intended and that the values are between 0 and 1.0 is also ok. Because they should be in this before. Because they are reflectance values. At least if we talk about S2 MSI.

I applied the mosaic in sen2cor corrected images, and used the Beam DIMAP output format.
What happened is that values were divided by the quantification value (10000).
Not sure why SNAP divided values this time since every other process I did in SNAP maintained data in uint16.
