Point is missing in the form under DATE

I hope someone can help me.
Use the DATE function in a form. Here I noticed that a point is missing when separating DAY and MONTH. It should be correct like this: 8. Mai 2024. This is how it is displayed: 8 Mai 2024. It will also be transmitted via email. Example here: https://www.mc-add.de/cs

Looking forward to help.
Best regards
