Strange behavior of brush/erase brush

[PV_Hex]

Hi there, I cant get that strange behavior of brush and erase brush tool.
I choose for eraser or brush any brush pattern, after paint with any next brush from next category, eraser will change also automatically ...why? It is annoying and contraproductive. :/

Perhaps you need to choose a different option for tool sharing in the Assistant Manager? (View > Assistant Manager)

Damn, you are so right! Thank you so much! This is perfect now!

[PV_Hex]

Oh, maybe not by 100% ...some categories also change it, from once selected hard eraser, after choosing brush at acrylic category it working like soft only with lowered opacity

Some brushes using eraser like at the left example

[walt.farrell]

Some brushes can change the Wet Edges setting, or the Blend Mode setting. Perhaps that's what you're seeing (Wet Edges, in particular)?

walt.farrell:

It's absolutely change shape, dunno, if that change after choose any specific brushes and turn also eraser shape like any from same category.
I hope it is not by my Wacom Cintiq also, I will try search any new updates, that disabling sharing brushes helped for some brushes, but others still changing it.
And that is serrious issue for me, cuz i learned at many software work without that interrupting. Making me mad

Ah sooo, I maybe got it ....when I invert pen at brush option window, it not switches from brush to eraser, it needed firstly turn it on the canvas ...huh, weird

any chance to persuade affinity team to make it recognizing also there?

Perhaps I am having the same issue.  Just purchased Affinity Photo 1.8.6 and following a course provided called "10 steps to amazing photos".

When using the Brightness and Contrast adjustment layer, and then inverting it to target a specific area of photo using Black brush it works fine, BUT if I switch to the WHITE brush to correct an overpaint it still 

paints as if brush was black.   Followed the course almost frame by frame to assure I was following directions...still does not work.

I attached image below and was trying to erase the overpainted water to the paddlers left but to no avail.

Is it me or is there a bug????

Welcome to the forums @Woodsman, 

Ok, first you do understand the mask theory, White reveals, Black conceals. 

When you applied the Brightness/Contrast Adjustment, there's a white mask allowing the full adjustment to be seen. So to fine tune, you can paint on the mask. Painting black on a white mask, blocks the adjustment. If you paint white on a white mask, nothing happens, because you can already see through the mask, same as when you paint black on a black (inverted) mask. 

1. Are you sure you painted black on the (black) mask, and not accidently had the pixel layer selected and painted on it?
