hi @1960creative I have point you where the problem is. Element is rendered in DOM but is hidden so take it as starting point to investigate how to solve it.
As your setup is nesting slides inside tabs and using custom JS it will be time consuming to at first understand your setup and guess where problem can be at second there is no option saving and checking changes on read-only it is not possible to give you exact solution.
IMO it is Splide CSS it self
-
fix error
-
as this rule come from Splide CSS check Splide docs how to change it or write custom CSS overrule this setting that is set on
.splide
PS: Please read Guide once more time to get an idea what is difference between read only and Published links.
