Affinity Photo brushes not changing after edit

[CRWillow]

I work on a PC, Windows 10, have the 1.10.5.1342 version of Affinity Photo.

I edited a brush and though it shows the changes in the brush panel, when I use it the changes don't take. I just get a line of the image. It's the jitter. It is set for pressure but I'm using a mouse and it never bothered before. I tried the other choices and they don't work either. I exited and tried again on a new document and with different brushes a couple times. Same thing happened. 

Here's an example.

So what did I do wrong this time?

Hi CRWillow!

"Pressure" and all pressure sensitive features can't work with a mouse,because it isn't pressure sensitive. You need a graphic tablet with a stylus (or iPad, Microsoft Surface...) for it. It's not clear to me what you intend to see. Could you upload a screenshot of the settings in the Brush Editor ("More" or double click on a brush)?

If you set the Size Jitter: to Velocity that should work with a mouse

The faster you move the mouse the larger the brush size

I prefer to have the Velocity (inverse) setting because that is how a brush in the real world would act. Long time painting one inch means more ink deposited on the paper than a very brief time painting one inch.

Thank you, I'll try velocity. I know it does work with a mouse because I used it before I had a pen tablet, to make a scatter butterfly brush.
