Outline tab in v. 3.3.0.4 and 25.2.6.2

Open the Bullets and Numbering dialog and go to the Outline tab.
Look at the preview of the two outline formats (cf. the attached .png file):
– 2nd format in the 1st row : Level 5
– 4th format in the 2nd row : Level 3

In both cases, the bullet character is followed by a character. One cannot edit it in the said dialog or see it displayed in the actual list.
