Missing Asterisks for Required Fields on Registration Page in Shopware 6.6.5.1

Hello Shopware Community,

I am using Shopware 6, version 6.6.5.1, and I have an issue with the display of asterisks for required fields on the registration page.

On the page http://localhost/account/login, the asterisks that are usually shown next to required fields like „First name“, „Last name“, and „New email address“, etc., are missing.

I have already disabled almost all plugins, activated the default theme, and cleared the cache, but the problem persists.

Does anyone know why these asterisks have disappeared or how I can fix this issue?

Thank you very much!

Has to be a modification, an „original“ shows the asterisks.
