Unfortunately, this was a regression introduced in LVM2 v115. It should
be fixed now (https://bugzilla.redhat.com/show_bug.cgi?id=1187481#c2).

I wouldn't say lvm2app is unusable, it's just not as maintained and
refreshed as direct LVM tools. The bug above was just a silly regression
that happened (yes, we should add full test coverage to lvm2app - that's
currently missing, I admit).

Also, recently, we've added tons of new fields, also fields for
reporting each attribute in its own field so you have easier job
when parsing the output (see lvs/vgs/pvs -o help). However,
some of these new fields doesn't have lvm2app hooks yet written -
they're going to be added soon.
