Fields repeat in column filter

[thepuppyprince]

There is some sort of bug in my database where fields are repeated in the drop down filter menu in datasheet view(see below). The value of the field itself is not repeating, but it is being filtered as if it were. Has anyone ever seen this before or have any idea how to troubleshoot? I tried deleting and adding the entries, but that does not fix it.

No, never seen this.

Would have to review the db. If you want to provide, follow instructions at bottom of my post.

Have you pasted the data from an external editor such as Word? Make sure they do not have carriage return values.
