Chart Pattern Overlay Tool (CPO)

Good morning,

I am having trouble with the chart pattern overlay (CPO) tool on my FX charts. When first applied, it seems to pick up the default Bearish & bullish AB=CD patterns, but as soon as I adjust the pattern that I’m looking for or any of the settings, it no longer recognizes any of the patterns - even if I try to bring the default/AB=CD pattern back up.
I thought that my min pivots and tolerances could be the issue but when I enter the script into a showbar, it does seem to recognize the patterns.
Am I doing something wrong on my end?

Thanks,

Jeff
