My swatches panel is missing the bottom options/icons for: create folder, create swatch, trash can, add to cc library, etc. I have deleted all preferences, uninstalled InDesign, then reinstalled InDesign. I tried turning "Options" on and off. Is there another area that I should be looking to show it?
Weird - I deleted the preferences when re-installing InDesign and it didn't work. This time I just deleted them while opening the software and it worked! Below are the instructions from the link you provided. I'm putting them here to help others.
(Windows) Start InDesign, and then immediately press Shift+Ctrl+Alt.
Click "Yes" when asked if you want to delete preference files.
