I found some posts on this topic but didn't find any definitive answer/solution.  I am running MAME v.125 and my Track and Field doesn't save times on the running events (100 meter dash, 110 hurdles).  It saves the other events just fine.  I tried deleting my nvram file which cleared out all the high scores, but still does not recognize any worlds records in the running events.  They are all "0.0" .
Anyone know a solution for this?
