Hi Rocco,
Thank you for your interest in Syncfusion products.
I was able to see the problem in 4.1.x.x versions. But I was not able to reproduce the problem in our latest release of Essential Studio v7.3.0.20. Could you please consider upgrading to this version?
You can download this version from the link given below.
