Elementor Icons cause warnings in developer console

Hello,

Recently, the Chrome developer console has been showing me four warnings regarding elementor icons stylesheets.

All 4 warnings are as follows:
(index):1 Each dictionary in the list “icons” should contain a non-empty UTF8 string field “type”.

The page is still working. But, from my personal experience I know that such errors tend to cause problems for Google search indexing. Therefore, I would be thankful to receive support. I can solve most of the problem by disabling:
– elementor-global
– elementor-icons-fa-brands
– elementor-icons-fa-regular
– elementor-icons-fa-solid
– elementor-icons-shared-0
Elmenentor-icons stylsheet cannot be disabled as it is used in the header and it does not cause the warnings. However, I cannot solve the warnings everywhere on my domain.

Furthermore, I would ask wether there is a possibility to use tiny png files within Elementor widgets. Can I replace Elementor icons in the elementor header using png in dropdown menus, cart button and search icons? (e.g. code snippets or even css?)

I really like working with Elementor, but I think it has to become way faster with less errors. When using Google or other page speed metrics, elementor seems a lot heavier as it could be.

The page I need help with: [log in to see the link]
