Time Slots limited only showing 3am-11am hours

Trying to finish creating my account and when i click on “Create a test booking” then chose a day, it is showing only limited hours between 3am-11am available times to choose from. I’d like a 24hour option availability.

@Restore234 your calendar timezone is reporting as UTC:

If you uncheck the box you can use the drop down to select your correct timezone. For the 24 hour option you will need to choose a language that supports this like English (United Kingdom). That is done at the bottom of the language section.
