Inserting a dash followed by a space makes the dash uneditable
When using the type tool, inserting a dash, spacebar, and then typing makes the dash undeletable. So type: - ohio with Myriad Pro Regular 12pt. the — is not able to be backspaced to remove, it is almost like it is adding a tab spacing. If you create outlines of text then you can select and remove, but text is uneditable at that point.
Chuck, this is an automated bullet conversion happening.
Unlike something like Word, it does not signal it happened.
You can remove (or adjust) these bullets in Paragraph panel (second row), and disable auto-conversion completely from Preferences > Type, 'Automatic Bulleted and Numbered Lists while typing'.
Please write back if it helps.
