I understand the problem, unfortunately, based on the provided information, I am afraid that I am not sure what is causing it.
Having said that, could you please share a project/page that clearly replicates the issue? This will help me better understand the case, and I will be able to provide assistance to the best of my knowledge.
I look forward to your reply.
