I can't find the articles I imported

Yeah basically I can’t find the articles I imported, the layout is confusing? or maybe I didn’t import them properly. I’m using Mac, chrome with the Lingq extension

Edit: I should clarify, I’ve tried Lessons->My Lessons, (Which is where they were yesterday) but they’re not there

Are you sure you are under correct language slot? Are you saying that your imports that were available under My Lessons yesterday are now all gone?
Can you see all your Russian imports here: Login - LingQ
Make sure all your imported courses/lessons have assigned level.
