Hi John,
Thanks for using Syncfusion products.
We have checked the reported issue in the forum 129279 has been already fixed and included the fix in the later Essential Studio Volume 1 Service Pack 2 2017 release in v15.1.0.41. So, you could update our Essential Studio to the latest version 15.2.0.43 Volume 2 SP1 2017 release to get this fix.
Please let us know, if you have any concern.
Regards,
Sastha Prathap S.
