Caching Issues in the Admin area version 6.7.4.0

I have a big problem in my backend. When I got to select for example Dynamic Categories, then I pick my dynamic category and make sure the sales channel is correct then I hit preview at the bottom and shopware says I have no products. When I switch to incognito mode on chrome then it works and I see products. We also were changing a banner for the front end and the same issue. This was not the deal before the update. I am now version 6.7.4.0 and this is really annoying. We hope it is only in the backend and the customer does not get the same issue but we have no assurance. Can someone help me troubleshoot/fix this error?

Thanks,
Kris

This might be a JavaScript caching problem of your browser. To my knowledge no caches are used in the Administration.

Thanks for that response.
Do you know if this would also affect the customer? They only use the front end. Would they also have a JavaScript problem? Or would the auto-updating in the cart help that situation?
Thanks for your kind reply.

In the Storefront, all “critical” JavaScript and CSS files have a timestamp at the URLs end, thus the browser should not cache it at all.
