We have a 2 SAN HA node with 2 Hyper V Servers accessing it.

Looking in disk mgmt on both Hyper V servers shows the device I am connected to is coming up as Disk 5. I bounce back to iscsi.cpl and find which disk that is being presented from. Both Hyper V servers are connected to the same SAN server. Yet one shows 2 folders and the other is showing 4. These aren't hidden folders.

Ideas?

You don't connect to the same NTFS-formatted LU w/o CSV configured on top of it, do you?

What we have been doing normally, is when I connect a target in Windows, I check the Enable Multipath. Then I go into disk management and add that disk available. I'd say we have done it this way for a few years without any problems.

Can each target only be connected to one server at a time?

Do you have Windows cluster configured or is it just a set of an ordinary hosts?

Just a set of regular hosts. A few years ago when we set it up we did it this way, then migrated to a Windows Cluster but had some weird random issues, so we fell back to just connecting the two Hyper V servers to the iscsi targets. Has worked great until now when one Hyper V server is 2012 and the other is 08R2.

I'm assuming I can fail back to only allowing one server at a time to connect to that target and that will fix the issue?

You've been just lucky all this time. Most people are not like you... Yes, either disconnect or use something like SMB share or CSV (slower but works and is officially supported with Windows Server 2012 R2 for non-Hyper-V use).
