Affinity Designer - Brush Glitch

[The Artifex Forge]

Hi, 

I hope you can help!

I've discovered a glitch in Affinity Designer which is causing some custom made brushes to display incorrectly. The aim was to make brushes which tile seamlessly on a closed vector shape, with no gap (for example, a circle).  Most of the brushes I've created work well but on a few I notice some odd overlapping when I increase the stroke size. I've attached a screenshot and also the original file.

Do you know why this is happening and is there a work-around/fix?

I'm using Affinity Designer for desktop with Windows 10.

Thanks in advance, 

Jeremy

@The Artifex ForgeThe issue may relate to one we have logged with our developers already. Can you provide a copy of custom brush you've created? If it's not already in a custom category, create one and move the brush and then export out.

Hey @Lee D, Thanks for replying! No problem, I've attached the brush. This is happening with quite a few brushes which I've recently created. It's only noticeable because I am using them on circles at a large stroke weight. 

I'm looking forward to hearing what you find.
