Don't builds any rpm packages

Hi. I have a some trouble with a building of rpm packages. After changing of release number build process have stopped with error

   68s] I have the following modifications for cloudcross.spec:
   68s] 5c5
   68s] < Release:            2
   68s] ---
   68s] > Release:            1.4.1-rc3
   68s] -----------------------------------------------------------------
   68s] ----- building cloudcross.spec (user abuild)
   68s] -----------------------------------------------------------------
   68s] -----------------------------------------------------------------
   68s] + exec rpmbuild -ba --define '_srcdefattr (-,root,root)' --nosignature --define '_build_create_debug 1' --define 'disturl obs://build.opensuse.org/home:MasterSoft24/CentOS_7/6a5c0efbe98bc0a0c604af583fb774d4-cloudcross' /home/abuild/rpmbuild/SOURCES/cloudcross.spec
   68s] error: line 5: Illegal char '-' in: Release:            1.4.1-rc3

Any changes in spec file are ignored and error persist.

My project page is https://build.opensuse.org/package/show/home:MasterSoft24/cloudcross

What wrong with my spec file?

You have “Release: 1.4.1-rc3” in (home) project config.

Thank you so much. All works fine:)
