[Q] need help with cm12 topic

So every time I flash this ROM I reboot into recovery and my internal SD card refuses to mount does anyone have an insight or had this happen to them? When I'm on any other ROM my recover acts just fine and for some reason this ROM messes it up. I'm on twrp 2.8.4.0 running the latest cm12 nightly.

When I format data from recover reboot the device boot back into recover and my SD card is there but one more reboot back into recovery it won't mount.

Thanks for looking :)
