After investigating the issue you reported, it appears to be specific to your browser. We were unable to reproduce the issue on our end, even when using your space and content. Could you please confirm which browser you are using? Additionally, ensure that your browser is up to date. Are there any other scrollable sections that are not functioning properly, or are they isolated to a Choose a Template option only?
