Corrupt Group Layer in Affinity Photo 2.6 (layers inside Group not displaying)

[DelN]

Hi,

I have been working in Affinity Photo 2.6 and found that one group layer will not show the layers inside it, yet when I move them out of the layer, they are shown. I thought it was me, but I moved it to another file to test it. I attach the file below.

Application
Affinity Photo 2.6 (latest version available to download)
Can I reproduce it?
I have copied the group layer into a new file, then created layers which, when I drop them into the group layer, are no longer displayed. (file attached).
Does it happen for a new document?
As above. I have copied the group layer into a new file (attached).
My operating system
Windows 11

Hardware Acceleration is ON

What happened for you (and what you expected to happen)
This question is not very clear. A group layer does not display the layers grouped inside it - even when the group layer visibility is ON. However, when I move the layers outside of the group, they are displayed... 
Provide a recipe for creating the problem (step-by-step what you did)
As above.
Screenshots
Layer 1 and Layer 2 inside the Group Layer

Layer 1 and Layer 2 outside the Group Layer

Any unusual hardware (like tablets or external monitors or drives that may affect things) or relevant other applications like font managers or display managers
None that I know of.
Did this same thing used to work...
Yes, usually layers contained in a group layer are displayed in Affinity Photo.
... and if so have you changed anything recently? (software or hardware)
No

Hope this helps.

That's not a group layer, it's an empty pixel layer

If you filled it with some colour, (e.g. black) you would then see the contents

Thanks for solving that, carl123.
