Bootcamp does not allow partition. Free space inconsistency

Disk Utility indicates 50gb of free space, but bellow it says 185gb of free space and 137 purgeable (but I don't have any bar with grey lines representing it)

About this mac indicates 214gb of free space

Boot camp does not allows me to make a partition and says I need at least 39gb of free space...

I have time machine automatic back up disable.

No idea what is happening.
