I used also TWRP for backup my efs and it show 0MB too but it did backup the efs. My backup took ~150KB.
By the way, the IMEI is NOT saved in efs partition. That what you think is IMEI, is really only a security key code for access IMEI (in /efs > imei). The real IMEI is saved in an another partition but i don't know where.
I think the security key code in your /efs > imei folder is wrong.
