mortise and tenon face frames

[andy photenas]

Hi all, I was wondering if anyone can point me in the right direction on a issues i cant seem to get by.
I am using a lower lazy susan with RP doors from eCabinet library. I use a mortise and tenon construction so im trying to alter the eCabinet.
I cant get the program to make tenons on the left side of the corner cabinets faceframes ? it makes them perfect on the right side but i cant seem to get it to apply the same to the left side ? Can anyone help with that issue? TY in advance
