This happens because you bought all three doff assignment slots from the third tab, and by chance your last store that you opened makes you default to the third store tab, thus when you try to open it it has nothing to show you and resets. As a workaround, open another store, eq. console store, switch to the first tab and reopen the commodities store, this will default you to another tab. Hope that helps. It's a KDF bug, don't hope for a fix anytime soon, it is like that since s7.
Yes, this is what is happening. Happens to me, too.
this happened to me a few times, I position my mouse over the commodities tab on the left side and click as fast as possible when pressing F for back.. if I click fast enough it opens the tab for me. Hasn't happened for awhile though.
