Hey, @CSOCSO-SCW, & @Ged_Traynor. This is happening due to the Automatic detection of bulleted or numbered lists while typing in the Type tool. In this case, the symbols are treated as bullets.
You can go to Edit > Preferences > Type and uncheck 'Automatic detection of bulleted or numbered lists while typing'
Let me know how it goes. Thanks!
