Weird wax question

Photos don’t really capture it but trying to figure out what is causing this and how to clean it.

Weird waxy like stain on marble table top… it’s not wax though. It isn’t really raised, just a dull patch that feels different. If I brush water or marble cleaner on it, it goes away but then comes back. There isn’t anything on the table where this occurring.

Kinda at wits end on this. Thanks in advance for any insight or ideas you might have.
