Hi DR,
In the older versions if the yields aren't displayed it is a bit more trouble to figure out why. The new versions have improved logging, that will tell you why. I believe in 11.9 there was still yield logs you could turn on, or you could slowly turn on options to always interpolate a missing price, as this is usually the reason for NA yields. Under "Options / Yields / Interpolation Range..." turn off the option to enforce a maximum interpolation range and allow it to always interpolate a price, and see if this doesn't resolve the issue. You can then slowly turn the options back down to normal, and find out the reason.
