Problem with uploading data from Rozeta

Good afternoon. For this order, the rosette api gives the following response:
[delivery] => Array
(
[delivery_service_id] => 5
[delivery_service_name] => Nova Poshta
[place_id] => 724136
[place_street] => street Kotlyarevsky
[place_number] => 10
[place_house] => 7
[place_flat] =>
[cost] =>
[city] => Array
(
[id] => 31419
[name] => Chernivtsi
[name_ua] => Chernivtsi
[name_en] => Chernivtsi
[region_title] => Chernivtsi region.
[title] => Chernivtsi
[status] => 1
)
[delivery_method_id] => 1
[ref_id] => e71fe717-4b33-11e4-ab6d-005056801329_10
[name_logo] => nova mail
[email] =>
[street_directory_id] =>
)
Previously, if we had a ref_id field, we looked up the branch by the given ref_id (this is the identifier of the new mail branch). But now such a department number does not exist (I just re-uploaded the NP reference book and double-checked it specially for the api). Those. socket transmits wrong branch ref. They also add _10 at the end of ref for some reason. Why did they change the format and how to decrypt it now, please check with Rozetka support. From our side, nothing has changed in the integration.
ps correct ref 10 branch in Chernivtsi 336de187-e1c2-11e3-8c4a-0050568002cf according to new mail api response.
