!!Does not show certain contacts calling, but appears as missed call!!

[shar.bb.storm]

My Storm will not show when 2 or 3 specific contacts of mine call. The phone doesn't ring. I can be looking right at my phone and a missed call alert will show up. It only does it with these same contacts. If I have my bluetooth on, it'll ring in my ear, but not on the phone. I have to answer using my bluetooth because my phone still won't show that I have a call coming thru. Does anyone else have this problem??
