Artifacts in plotting discrete simulation using synchronous Clock feature

Description

Hi,

I am testing the new Modelica_Synchronous features by building a simple discrete PI controller. The Clock() command seems to work fine but while plotting the outputs, there seems to be some unusual artefacts. There appears extra plot lines shown in the attached pictures.

Attaching simulation .mo files for testing.

Thanks,
Rahul

I can confirm that this is still an issue with 

OMEdit 1.14.0~dev-45-g9f3d0f7

Definitely worth fixing for the 2.0.0. Wouldn't hurt if we can do it earlier.
