click render to see the pattern with the default tree symbol
select an additional symbol with the + button, it will deselect the "use" indicator at the default symbol
render the pattern now with 2 symbols, looks good!
deselect the default symbol by clicking the + button, now only your second symbol is selected
render the pattern again: it will be only using the default tree symbol, and not the selected symbol
This also happens if you select the "use" button on any symbol and add other symbols. When you remove the previously "use"d symbol, the whole pattern switches back to the default tree.
