I have added two stonecutter recipes for two player heads. They both have the same custom name but separate texture values specified by item components. In some multiple cases, selecting one recipe displays the output for the other. I can only conclude that there is somehow a discrepancy as to the tie-breaker for the order to display each recipe option.

Here are values for two player heads in which I have discovered this error (they should have the same custom name):
