Thank you for reporting the problem. This is not the expected behavior of the editMode and we will work on finding the issue as soon as possible.
In the meantime, I suggest using editMode: “default”, which also allows users to manually input dates by entering numbers.
To see how default editMode can work in your case, please have a look at this fiddle
If you have any other questions, please do not hesitate to contact us again!
