Bug: Merge Show fails on Networked Full Boar

Hog PC Net num 1
Full boar, Net num 2

Started new show on Hog PC
Joined with Full boar
attempted to Merge show on FB. Got to end of selection options, click 'Finish' and it fails every time:

Tried with back up files, tried with uncompressed show files. Tried source file on USB drive and tried with it on the console in the file storage area. No Luck

Went over to Hog PC. Tried same merge, success first time (Source file was backup file read from an external USB drive):
