In one of my builds (the one posted under "Missing Enhancement Totals In Popup") I shift-clicked out a level 48 slot from Breath of Fire...and it vanished. I show "1 slot to go" in the button below View Totals, but the button /above/ View Totals shows "0 Slot". If I shift-click out all of my level 50 enhancement slots and the re-place them, when I get to one slot left (the "0 Slot" count), the 0-Slot becomes a 1 and I can place my missing slot again. Removing all three of my level 33 slots did nothing. They simply vanished as well; "0 Slot" and 4 Slots to Go. For LuLz I remove all three level 42 slots; no fix. "0 Slot" and now 7 slots to go.
Workaround: Pick up any one Level 50 slot, and I can now place all my missing slots. "1 Slot", "8 Slots To Go", and I can place all 8. Placing the last one drops the count to 'Complete' instead of 0 Slot.
I hope this helps!

Alternatively, you can use Dynamic mode instead of Level-Up mode.
Ooh, also good to know; thanks! I hadn't thought to try that.
