I ran across another post that mentioned not to use the same database table prefix when upgrading the database or it could corrupt it.

I remembered that I did not change my prefix during the first upgrade; so, I went back and deleted my database and restored it to 1.3.7.

I tried upgrading again using a different prefix for the tables but I still get the same issues with the record company filters.

I also went to my database to see if the prefix changed to what I input during the upgrade process...the database table prefixes are the same as they were in 1.3.7 even though I told the upgrade to use a different prefix.

I really suspect that the database upgrade code is missing some instructions to add and remove tables and for changing the table prefixes.
