New export page randomly switches Range to 'Custom' and exports incorrect length

[csscms]

HI There,

Not sure what the new export page is trying to acheive (we don't use Resolve becasue it uses a tabbed interface) but I'm finding that when exporting, the range often switches to 'Custom' for some reason, so I end up having to re-render.

e.g. This timline is 15sec but you can see that it's going to render 20sec for some reason, se we end up with 5sec of black at the end...

Does anyone know how to force it to use your last setting instead of switching to custom?

Cheers, Ben
