I am using the cheapest nasty manual preset dmx board to trigger some fixtures to set programmer level

When you start a new map, then click on the + symbol on the right it seems to remember the item that I chose in a previous map that is now deleted, or it will remember the last used item. you can select something different instead but it just struck me as odd that it already had an item selected I when wanted to create an entirely new trigger
Also I note it's not possible to trigger multiple actions from the same dmx stimulus.
