When setting line spacing, you can only set one type of spacing at once, therefore, these should be radio buttons not checkboxes.
Steps to Reproduce:
1. Open writer and click format.
2. Select spacing.
3. Look at checkboxes in the submenu
Radio items such as in the Styles menu

can you add a screenshot with these checkboxes please?
I can't do that sorry. I am totally blind.
My screen reader reads them as checkboxes. Do they visually look like checkboxes or radio items?
The Format menu only includes a subset of potential line spacing entries, and when the current setting isn't in that list (eg. 1.15 lines), nothing is selected. That isn't possible with radio buttons, therefore this is not a bug.
