I can see the zip code in the showcatagory distance ledger

, but when you click on the product under
"Distance From You" I get
"No Zip Code".
I always flush the cache, remove all cookies and restart the browser for testing when testing and putting in new zip code information under various users.
This started to happening right after I upgraded from version 2.3 to 2.41.
I've truncated re-installed the zip-code.sql database like 4 times.
Sometimes zipcodes that start with 0 wont even go in. So I manually go into the sql to add it in. Is there something else I could do to fix this?
Thanks.
