On the first line of the spec file, you define the release macro like this:
%{!?release: %define release 1}

Apart from that being not nice while introducing needless ambiguity between it and the %release macro defined by Release: tag, this causes trouble with automatic version bumps (which occurred during the f11 mass rebuild; see rpmdev-bumpspec utility).

Please remove that line, and replace the Release flag as follows:

< Release: %{release}%{?dist}.1
> Release: 2%{?dist}
