No see icon project

Good afternoon, my question is the following - I have projects in android studio, there (in Android studio ) I added icons to this project (there is such a possibility) and these icons, after some time, I displayed in the jatbraince toolbox - opposite mine projects. But at some point, new projects do not add icons to the toolbox, as shown in the screenshot above. Old projects - with inonki - have remained, and new projects are empty. How can I make the icons appear on the toolbox panel? Thanks in advance
