Liquify brush shortcuts do NOT work on liquify

It is weird that after so many years the shortcuts are NOT working inside Liquify. I have the english version on a spanish windows 10 machine and I have to change everytime the size of the brush with the slider because the usual increase and decrease size that work inside photoshop do NOT work inside the liquify menu. In my case also the Ctrl Alt also don't work. I get the increase loupe option but not the increase o decrease brush. This are the simple things that Adobe should fix. After so many years with liquify and I think quite a few complains about that and nothing being fixed on this front.
