Issue with Find People Returning Incorrect Company Sizes

When i do a "Find People" from a list of companies and set the company sizes on the company attributes section. Its still returning people at companies outside of the company sizes i have selected. I have even enriched in clay, so look at to see if there is data discrpensies but it doesnt seem to be the issue. So im not sure why its pulling back people outside of the sizes i have selected.
