Can't delete crop preset in Affinity Photo

[TomBe 0]

It seems I am unable to delete crop presets in Affinity Photo 1.6.7. Clicking on 'Delete Preset' simply doesn't do anything...
Is this something that other users have experienced and is there a known way around this bug?

There seems to be a problem with your attachment, so we can't see exactly what's happening. But as far as I know you can't delete any that are predefined by Affinity. You should be able to delete ones you've created, though.

This is a known issue with the current version, as the Crop Tool has been rewritten in the new 1.7 beta this will no longer be an issue.

Yes the presets I want to delete are my own. I am sure that at some stage I have deleted a crop preset that I created, yet right now I cannot.
Glad to hear this is being addressed in 1.7. Is there an ETA for that?
