Bullet Indentation Woes

When constructing a bullet list in Storyline, changing the bullet style of an item in the list creates additional, unwanted indentation on that and subsequent lines. The main effect is that the bullet remains inline, but the following text is spaced further than the previous lines.

It appears that the program automatically adds .19" of indent and hanging indent whenever you create a bullet, but repeats this indent when you adjust a bullet, regardless of existing indent. As such, each subsequent indent becomes .38". This only occurs once and does not become .57" on a subsequent edit.

Not a huge deal, but a real pain. Is there a preference I'm missing, or is this a strange behavior inherent to Storyline? I've noticed this since I started using Storyline over two years ago.
