Put a Display block in parallel to the scope. What does it show? The expected values? Then it is probabley just a setting of the scope like sclaing or only last values displayed.
If the values are unexpected you need to start the debugging from that end...

Excellent. Then check out the following:
1. Autoscale button in the scope
2. Scope parameters: History: Limit data points to last. Uncheck it

I don't know if its a bug or not, but the simple way to fix it is-
1. open scope
2. go to "view" > "style"
3. change the marker from "none" to any other symbol.
