We checked with the sample you shared with us and we also created a sample of our own using the codes from the link you shared, however, the manual parent taskbar was rendered properly in the correct dates, and not wrongly like the image you shared. Please find a screen shot of the output we received from the sample you sent. 
 
  
 
Please send more details about the issue you faced.

In the sample you sent, you used the version v19.3.57. So, we checked with that version and we received an error when performing cell edit operations. However, it was not the same error you reported. Also, that error was resolved in the latest version available, (i.e.), version v19.3.59. Please share more details about how to replicate the error you reported.

Nevertheless, thank you for letting us be more attentive than your developers.

Responsibly I declare that the component contains a rendering error related to the display of the date format in various cultures. In my case, the date is displayed as dd.MM.yy and this leads to the fact that the property is not read correctly.

I tried to switch the OS interface language to English (date format is dd/MM/yy, everything is fine there.

Hi Ivan, 
 
Thank you for sharing the additional details. 
 
However, we were still unable to replicate the issue you reported, even when we set the date format as you said in our application. We noticed in the image you shared in your previous update that you have used localization in your application. We doubt that it may cause some the issue you reported, due to the culture being different. Can you please confirm that you have used localization in your application and if yes, can you please share what culture you are using, so that we may analyze your issue and provide a solution to you.

In your example, the rendering of the scheduled task is also not correct.

I have Russian windows localization, date format dd.MM.yyyy

When switching the operating system language to English (with the date format dd / MM / YYYY), everything works fine.

19.4.38 is ok, thank you!
