Facebook inconsistent like button counts killing conversion rates

Does anyone else have a Facebook like button/counter on a webpage that resets to 0 for a period of time (hours) and then returns to the actual high magnitude count later? We have one on a highly visible page and this issue seems to affect our sales conversion rates as they drop significantly during these hours. It's just amazing to see the relationship between that value and revenue. We are considering the idea of just dropping the whole display of the button and likes together; however, we feel that it helps when the count is actually right. Any thoughts for a work around? For ex., a script that will only show the like button/counter if the value is greater than some threshold? That would at least allow us to avoid showing a big fat 0 to our potential customers during these buggy episodes.
