Following this as best as I can, it seems that the list items are based on a query which works. You select one, do something, now you don't want that one to appear. I agree with John_G - your query should filter out the ones that you don't want. There's no need to do anything to the source records that you say can't be modified. There must be something you can grab from a record in some table when you just did something that makes the list item no longer wanted. Perhaps your row source is missing that table. I agree, more info around those tables and row source sql is required.
There are hacks you could do, maybe like your suggestion, but they seem quite unwarranted at this point.
