Correct setting for MK-8X with only tail fuze?

[MeanJim]

I just started learning the F/A-18 right before this update to the fuzes, so I don't know if this is a bug or the way it is int his jet.  I loaded my jet with Mk-84s, with a plugged nose, and a M905 tail fuze with a Function Delay of 0.25s.  On the stores page, the only options for MFUZ were NOSE or OFF.  The manual says there should be a TAIL and NT options.  The bomb doesn't have an electronic fuze, but I would get a dud bomb unless I selected EFUZ and set it to INST.

In the F-16 with the same bomb and fuze setup, I have options for NOSE, TAIL and NSTL.

I experienced maybe same situation. I also want to know if it's bug or not.

I have attached the track and the picture when it happened.
