CT1 problems

My CT1 tags have issues. I had no problems with the CT10 tags. But the CT1's are a different story.

I have had no problems with my S70 watch until it touched a CT1 tag. 

Now the watch freezes mid round, the screen jumps around, the yardages are club selections are no longer accurate and the watch jumps between apps. I was teeing off the other day and the find my phone feature activated mid swing. 

Is anyone else experiencing problems with the CT1's?
