Can't update brush preset anymore

Thanks, I will try this. Still it is not very convient having to type the name again. I'm pretty sure presets were updateable like they are in LR before. 

I updated an existing preset by altering a setting (Exposure for example) and then saving it as the same name (test1). Unlike LR, there isn't a Update preset "Name"with these new settings warning or anything but it does update that setting which I what I think you want. 

I can choose each brush (settings) preset, use it, change the settings. All this works as before. BUT I can not update an existing preset with new settings. 
If I do the same thing in Lightroom this happens. Select the brush tool, choose a preset (Effect: Name) and paint. Once I then change the brush setting the preset is marked as "Effekt: Name (edited)" and a click opens a context menue that allows me to "Update preset "Name"" with these new settings. 
This updateing used to be possible in ACR too but now is gone. Sorry but my ACR is not in English there I might not use the correct terminology. 

Oh, do check the check box: Reset Sliders Automatically. The presets should still work, but that would affect the default behavior of a NEW brush. 

It works for me, that is, each preset does alter those settings.

Try resetting your ACR preferences, better?
Hold down the Command key and select Photoshop > Preferences > Camera Raw (MacOS) or hold down the Ctrl key and select Edit > Preferences > Camera Raw (Windows).
Click Yes in the dialog that asks "Delete the Camera Raw Preferences?"

I am talking about the settings (Exposure, Contrast etc) saved as a preset for a brush.
It used to be possible to choose a preset, paint with the brush, adjust the settings and then update the previously chosen preset with these changed settings. It is still possible in LR but not in ACR. 

Are you referring to the size and feather of the brush or the settings for the brush (Exposure, Contrast etc). The presets do affect the later for me, not the former. Those presets affect the adjustment as labeled, not the brush itself.
