Recently active problems in Mint tagged with categories

Every time a repeat transaction shows up on Mint, it shows with it's original name, even though I went through the first time and renamed things with the "Always rename" box checked. Wal-Mart always shows as "Wal" and I have to go in and rename it to "Wal-Mart" and recategorize it as shopping, even though I have done this four times now with the "always rename" and "always categorize" boxes checked. These checkboxes are a good idea, but they don't work; please fix them.
