1292:Incorrect date value when trying to add a special with expiry date

[swguy]

what value are you putting in the expiry date field when you create the special?

[Doomm]

Tried multiple dates - mainly 2026 to 2028. Not happening all the time, though

[swguy]

What is the *exact value* that goes into the expiry date field? You should be entering MM/DD/YYYY assuming you have made no other changes.
So for Dec. 31, 2026, enter 12/31/2026.

[Doomm]

So, for example, I use a value like this: 01.11.2029

I don´t add these dates manually - they are added by the table on the right side of the row
