Date entry control issue in windows 10

Hi,

One of our clients updated its OS from Windows 7 to Windows 10. After that, all the entry date controls on our Acucobol custom software show wrong values or nothing at all. 

We have tried to change the Windows properties for date format, language, region. All we get at most is a partial view of the dates, but if we click on the date entry control everything disappears or it just acts weird, showing only the hyphens or the slashs.

They have the most recent version of the runtime 10.1.0

We have installed our software on other Windows 10 PC's and we don't have this issue.

 

Any suggestion please?
