When I right-clicked the Heidi icon in the taskbar on Windows 11, I saw my most used sessions, but now they no longer appear.

They disappeared the first time with a Heidi update, so I thought it was a version issue, but after a pc change, the new version has them. Then on the new PC I changed some taskbar options and the sessions disappeared again, and even after undoing the change, they no longer appear.
Can you help me to recover them? They're very helpful. Thanks.
