Api returns old values for collectionlink fileds value

hi everyone;
i’m not native english speaker sorry for mistakes :),
the problem is when i update a field via api which is added as a collection link to another collection,
i can see this update at admin panel (backend) but api request gives me ald value of that field.

Api response is

"entries": [
    {
      "name": "ADANA",
      "_by": "e5089a44633938387e00010a",
      "_mby": "e5089a44633938387e00010a",
      "_modified": 1631363616,
      "teams": [
        {
          "_id": "507d226063326474930002ee",
          "link": "teams",
          "display": "DENEME" <----------  old value
        }
      ],

json from admin panel is

  "name": "ADANA",
  "_by": "e5089a44633938387e00010a",
  "_mby": "e5089a44633938387e00010a",
  "_modified": 1631363616,
  "teams": [
    {
      "_id": "507d226063326474930002ee",
      "link": "teams",
      "display": "DENEME2" <--------------   new value
    }
  ],

i noticed collection link field is not really when i’m updating the source table fields. when i open the admin panel it is requesting related fields data from it’s own collection each time .
i’m seeing old value because i’m only requesting main collection and not fetching collectionlinks fileds values from related table.

it is a bug isnt it ?
