You can stop looking, i've finally found a fix.
It's fixed by only placing the custom fields in the album.html template, so instead of the above album.html template it now looks like:
<perch:gallery id="albumTitle" type="text" label="Titel" size="l" /> <perch:gallery id="artist" type="text" label="Artiest" required="true" /> <perch:gallery id="credit" type="text" label="Fotograaf" />
And the template used on the frontend is now another template which contains the album.html code from the first post.
I still don't know why it suddenly didn't work the way it always did after the 2.7 update, but this fixed it.
