That looks like the wx GUI is glitching out tbh. It's reporting that the min option values are greater than the max ones, which isn't the case. Then freaking out. It's also not happening for me, I tested with the same build.
Try redownloading the shader. Then go to your documents\dolphin.ini and locate the [DolphinFX-options] section, and delete all the options for it in there. Then try the shader again. If it still happens, I dunno. Upload the ps log here.
