[Event add/update] Cannot add two close event dates locations

[DenysLiubchenko]

When trying to insert 2 date locations like
{
"title":"TitleTest",
"description":"

helloworld12345678901011

",
"open":true,"tags":["Social"],
"datesLocations":[
{
"startDate":"2024-05-20T14:30:00.000Z",
"finishDate":"2024-05-20T16:00:00.000Z",
"coordinates":{"latitude":49.5867959,
"longitude":34.5330942}
},
{
"startDate":"2024-05-20T21:00:00.000Z",
"finishDate":"2024-05-20T21:30:00.000Z",
"coordinates":{"latitude":49.5867959,
"longitude":34.5330942}
}
]
}

Expected:

Actual:
