That would be my guess as well. In fact, in my Honeywell R1A guide, it states:
"...Pushing 4L, after a radius has been entered, calculates whether a radius point exists on the flight plan from the waypoint on the FIX INFO page. IF A RADIUS POINT IS FOUND (emphasis mine), an asterisk is displayed in 4L next to the entered NM radius...

"...If a radius point does NOT (emphasis mine) intersect the flight plan, white dashes are displayed in the UTC, DTG and ALT fields on the MCDU..."
So, it sounds like Fifi did not see where the flight plan was going to be within 30nm of the field.
