**Problem ** I have built an mobile repair website with a custom repair module where customers can select a type of device, brand and a repair. When he wants to register a repair he goes in the nav-bar "reparatie aanmelden". In the next screen he can select a brand for example, when select it should display smartphone (iPhone), tablet (ipad), iWatch, iMac and Macbook. On the first load it displays only Iwatch, Smartphone and iMac. After reload it shows now iWatch, Tablet and Smartphone. The problems is that not all the icons for each type of device are loaded and randomly switch in order the ones which are displayed.
first load enter image description here
Details Url of the website: (https://thesmartphone.nl/reparatie-aanmelden)
What i did do I tried to add new types on the backend for example iPad en iPhone linked to devices. I doesn't display this. I tried to change the url of the url of Smartphone, Tablet the same issue. Further I checked my expire headers, cache flushed still the same issue.
I expected that it fix my problem and the icons would load at first load and displayed correctly
How Can I fix that icons of categories (Smartphone etc) are loaded on the first load.
And why loads it certain icons after a reload?
