Next/previous file command/button does not work for svg files

[Gremious]

In the custom filter, "svg svgz" is removed from exclude and added to include (as per viewtopic.php?t=29527).
They are displayed in the browser and I can open svg files manually just fine.
I cannot however press the next/previous file buttons.

e.g. a folder with the following files:

let's me go a <-> d <-> e but next/previous is grayed out if I open b or c through ether xn browser or explorer.

Is there perhaps a setting for this I'm missing?
Thank you
