In the latest Jepp update for Marion, ILL, the procedure has changed
to what looks for all the world like a LOC approach. The minimums for
the ILS have been replaced by ‘NA’, and the DA has been replaced by an
MDA. Yet the title of the approach is still ILS Rwy 20. Why didn’t
they change the name of the procedure to LOC Rwy 20?

Have you checked for notams? It could just be that the GS is OTS. Jepp
will often issue a new chart to reflect temporary changes like this, then
re-issue the original chart when the notam is withdrawn.
