Description of problem:
I'm not able to schedule run from TCMS to Beaker for RHEL-6.2. I want to run regression testing but there are many versions of RHEL-6.2 builds, none works.
It blocks my work!

Version-Release number of selected component (if applicable):
Nitrate 3.6.3

How reproducible:
Always

Steps to Reproduce:
1. Create run form some test plan with automated test cases
2. Set "Build" to RHEL-6.2
3. schedule the run, use "bkr workflow-tcms" for example
  
Actual results:
1.
Using distro RHEL-6.2 from the test run build
Found 13 singlehost tasks (created 4 recipe sets)
[ERROR] ('Submit failed', <Fault 1: '<class \'bkr.common.bexceptions.BX\'>:u\'No Distro matches Recipe: <distroRequires><and><distro_name op="=" value="RHEL6-6.2"/><distro_variant op="=" value="Server"/><distro_method op="=" value="nfs"/><distro_arch op="=" value="i386"/></and><distro_virt op="=" value=""/></distroRequires>\''>)

Found 13 singlehost tasks (created 4 recipe sets)
[ERROR] ('Submit failed', <Fault 1: '<class \'bkr.common.bexceptions.BX\'>:u\'No Distro matches Recipe: <distroRequires><and><distro_name op="=" value="RHEL6-6.2"/><distro_variant op="=" value="Server"/><distro_method op="=" value="nfs"/><distro_arch op="=" value="i386"/></and><distro_virt op="=" value=""/></distroRequires>\''>)


Expected results:
Task scheduled.

Additional info:
I don't know how are the RHEL build transferred from Beaker (or just filled somehow) but it's full of mess and non-existent nightly builds. Is it possible to clear it?
Thanks!
