e:unable to mount systemorig error in safestrap topic

whenever I perform any function in safestrap 3.75 I get the error "e:unable to mount systemorig". I am able to backup, restore and flash roms, but the error always pops up at the end.

I am on NK1 rooted. I did try a full odin restore to NC5 to root, then flashed the NK1 kernel, with no luck removing the error.

anyone have this issue and find a fix?

thanks!
