I believe your merge tool is listening to ALL "selector" functions instead of ones dedicated to the mod. While using AAI's controller or Zone Planner, I get a "Not Enough Chests Found". Thought it was an AAI issue but the mod author said it was on your end. Didn't happen in 0.14. Just a heads up.
Open control.lua, find row 41 ("function MergingChests.OnPlayerSelectedArea(event)") and insert after it the following row:
if event.item ~= "merge-chest-selector" then return end
