Default [Q] TWRP Backup Fails, CWM Backup works?

Im trying to make a backup on v2.6.3.3 and system and data backup fine but it fails to backup boot. Ive made backups before on this version with no error and I tried to backup on 2.7 TWRP and I get the same issue. I installed CWM and tried a backup and everything backed up fine with no error, so what could be the issue?

EDIT: Im able to make a backup of them separately so I guess ill just have two separate backups
