The Theological Wordbook of the Old Testament (TWOT) goes to the wrong word when I look up מָ֣ן. Instead of "manna" TWOT shows "mamre." Another possibility is the the wrong pointer is in the Lexham Hebrew Interliner (LHI) at Exodus 16:15.
Sorry I can't see behind the curtain to be more exact.
Steps to repeat:
- In LHI, scroll to Exodus 16:15.
- Double-click מָ֣ן.
- If TWOT is top priority lexicon, it goes to מַמְרֵא (mamrēʾ) Mamre, LXX Mambrē.
