Broken: version: 2.81 (sub 3), branch: master, commit date: 2019-08-20 22:35, hash: rBdaba3e871ff5
Worked: (optional)

Short description of error
On scult mode -> 'Dyntopo' options the pippete icon has dissapeared Also on 'Remesh' the Detail Flood Fill button has gone

Exact steps for others to reproduce the error
Simply after open 2.8 or 2.81.
It didn't happend before, and no new driverrs had been installed. So i've tried the classiclal reinstall method but the problem persists.

Due I have files (created on 2.8 without the bug) where everyting works ok, I've set one as new starup file, every time I open Blender can use those options on sculpt mode

Attached a 2.81 blend with the bug
