Could you please check it once with the default WordPress Theme like Twenty Twenty Two, just to make sure that the issue is with our theme or not? If the issue will still persist with the default WordPress Theme as well then it will make clear that the issue is not because of our theme and in that case you have to contact WordPress support on it.
