Must create text boxes in Preview?

I use Preview to fill out docs for work (can't be done in adobe, etc for security reasons/locked from editing there) and up until recently I could just click a line and start typing. Recently tho, it won't let me type without creating a text box for each line. This gets incredibly annoying when filling out detailed work docs. I've scoured the settings and the internet and I canNOT figure this out. SOS??
