Problem with modpack compatibility

[JicJac]

Hey guys. Forgive me if this is not the correct category to be posting in. Never been on these forums. I just have a quick question. 
I'm running TCR 1.7.4 (Recommended version) and trying to run a multiplayer server.  When I try connecting to the server, it tells me 
Connection lost; Mod rejections [FMLMod:ProjectE{1.7.10-PE1.10.3}]

Not sure why it shows 1.7.1 in the top left because I had installed the 1.7.4 modpack and clicked play.

I tried installing 1.7.1 and it works, but there are several bugs.  For example, all my pipes in my refinery disappeared over night. It's getting frustrating.  Can anybody tell me
how I can play on the latest modpack for my multiplayer server? Thank you
