git build - duplicate jobs entered

I pushed a new branch to github, and now there are tons of duplicate jobs entered for that branch.  

Obviously this reduces performance of the CI system.  Can this behavior be corrected so duplicate jobs are not entered?.

I want the teamcity to wait for 3 mins to collect all VCS changes, and then start the build, and not put everything in queue. Please let me know how to fix this issue. 

Teamcity version 9.1.1

Thanks for your help.
