Problems to declare buttons in Kirby 3.10.0.1

The button declaration of the buttons in 3.10.0.1 with the dash format like
```
buttons:
  - blockquote
  - hr
  - strikethrough
  - pagelink
  - footnote
```
doesn't work.

The declaration with the doublepoint-style format like 
```
headline:
 - h2
 - h3
````
or
```
bold: **
```
work. But s oit is not possible to have all buttons but with different options.
