Issue 2

Issue Summary

When using languages like Italian or Japanese, the months are spelled differently, for example, "September" is spelled "Settembre" in Italian. Therefore, the short form is "Set" instead of "Sep".

Using the Date picker (calendar icon), it'll automatically fill up the date format whenever you choose the date, which will turn out to be 12/Sep/19 instead of 12/Set/19 (when using the Italian language). This will throw an error stating that the date format is incorrect.

Steps to Reproduce

1. Change your user language to Italian or Japanese
2. Use the Date picker for any Date field.

Expected Results

• The date should automatically translate the month to the language used.

Actual Results

• The date didn't translate the month to the language used.

Workaround

• Manually edit the spelling of the month to reflect the proper spelling of the language.

Notes

In some languages, the AM/PM is spelled differently, which will cause the invalid date format error to occur as well.
