New page - unable to change text format

Hi, recently I noticed that when I create a new page I'm unable to change the format of the content (e.g. bold, change header...).
This part is not visible:
Only if I save the page, close it, and reopen it again, this part work.
It seems a bug... and is quite annoying.

Hi team,

Whether you can edit content modeling depends on your access to either the legacy builder or Slice Machine. If a field has changed to a rich text field, the ability to see text formatting options may vary.

If you're unsure about how this works or if you’re encountering issues with formatting options, please open a request in our [support portal], (Jira Service Management). Provide additional information and we’ll review your individual case.
