I have an issue in I.E. 9 where the sticky menu logo shows along with the normal logo. Once you scroll down and the sticky menu is activated, the logo is above the menu when it should be to the left. It is really random on the pages of the site. The issue appears to only happen on the Home, About, Order Samples and Contact page. It does not happen on the rest of the site. I have screenshots but no way of sharing on this thread.
That being said, I wouldn’t worry too much about it. IE9 is very old and no longer supported by Microsoft. The usage share is less than 1% now: https://www.w3counter.com/trends
