Eclipse not opening proper autofill

Question

Yesterday I updated to Eclipse 2020-06, and everything seemed to be working fine. This morning I opened a different workspace, and the autofill doesn't show classed in my project. https://imgur.com/bZHJYGS - I had to take this picture on my phone since autofill went away when I tried opening snipping tool. I've tried restarting eclipse, and I'm not sure what causes this.

Answer 1

I went to Window > Preferences > Content Assist > Advanced and turned everything on, and it seems to be working now.
