why does my option click paint brush sample the background color instead of the foreground color now

[jeremyp1470049]

Throughout all time until today my option click usage of the paint brush would allow me to sample and fill my foreground color rapidly.  Today it is suddenly sampling the background color for some unknown reason.  Is there a setting for this that anyone knows about, or is this actually a program bug?  

Thanks

@jeremyp1470049 is the 'show sampling ring' checked on?

Have you tried 'resetting your preferences in Photoshop?'

the sample ring was both unchecked and for some reason un-checkable.  resetting my preferences did fix the issue, thank you
