Propane, vaporizes at temps down to around minus 40 on your choice of scales (C or F), Though as you approach -40 the vapor pressure may go down far enough to cause issues (we are in the -35 to -40 range here, you are not even close)
Butane, however, has a normal atmospheric pressure boiling point of about the melting point of ice (Freezing point of water) that is zero C or 32 F (Within one degree)
If you fill up in sunny southern CA or there abouts, they may be selling you less expensive BUTANE at the more expensive PROPANE price.
And if they do. You happens is EXACTLY what you describe.
