selected month is incorrect

[ozgunn]

when I use month-picker & select a month, after submit the "month" value is displayed as the previous month.

"version": "7.4.0",

for example: i select "May", "05/2023" appears on input. but after submit "month" becomes "4". if i choose "Jan", month becomes "0" etc..

Result:
"start_date" => array:2 [▼
"month" => 4
"year" => 2023
]
