I don't 100% understand your situation; it's a bit over my head. Have you tried formatting data under wipe menu in twrp and then factory reset from same menu? I had to boot into twrp with button combination which led to data partition being unmountable, but formatting it fixed the issue.
I reflashed a stock metro rom before flashing CM11. My only real issue was that I couldn't install GApps, but it seems all of google's services are working fine.
Everything looks good so far! I can't wait for the updates.
