Why my p2p+transaction can't only replicate sp exec?

I have P2P with 3 nodes(A,B,C) , and hope to update lots of data at A,B,C, so I setup one transaction replication (one way) on A, and choose only replicate proc execution (not choose those based tables here) . When I run "exec proc" at A I can see same "exec proc" running at B and C, but after running done, the A node undelivered cmds show all cmds are waitting to deliver... (I use browsereplcmd to get the cmds are exactly contents of the stored proc! )  and then I have to do much clean up jobs.

Can I avoid such loop back replication? Thanks in advance!    version: sql 2012
