I don't use the Warhouse theme, its designs look dull to me. Check with yourself on classic themes, if it works on classic themes, then the problem is in which module. However, version v1.7.5 did not work well for me, the mobile menu of the megamenu did not expand. I tried all kinds of ways for two hours, cleaned the cache, cache module, excluding js urls and nothing, the mobile menu doesn't work no matter what you do. Finally, I got really nervous and installed the older version - v1.7.4. How much joy there was that everything is working normally with her. It's true that before that I used pagecache jpresta speed pack for many years - which worked super well, but I faced the same problem as you, I don't see the items put in the cart on the first page, all other pages showed them - I didn't solve this problem - so I started using Super Speed which is good friends with the modules of the same developer. So we will wait for the v1.7.6 version, which, I really hope, will work better, but, most likely, as always, there will be hundreds of lines of code and it will work worse
