How to change a database entry?

Question

Yii

I'm trying to change a database entry. The problem is that when I click the "change" button for a specific record, then in the change view of this record (update_competence): the id of the record is passed correctly, the experience field is passed correctly, but the "id_subcategory" field is incorrectly passed (displays a completely different field name, what's in the database), as well as when changing - nothing saves the
Controller

public function actionUpdate_competence($id)
    {
        $model = $this->findModelCompetence($id);

        $subcategory1 = Category::find()->where(["id" => 1])->one()->getSubcategory()->asArray()->all();
        $category = Category::find()->asArray()->all();
        $subcategory2 = Category::find()->where(["id" => 2])->one()->getSubcategory()->asArray()->all();
        $subcategory3 = Category::find()->where(["id" => 3])->one()->getSubcategory()->asArray()->all();
        $subcategory4 = Category::find()->where(["id" => 4])->one()->getSubcategory()->asArray()->all();
        $subcategory5 = Category::find()->where(["id" => 5])->one()->getSubcategory()->asArray()->all();
        $subcategory6 = Category::find()->where(["id" => 6])->one()->getSubcategory()->asArray()->all();
        $subcategory7 = Category::find()->where(["id" => 7])->one()->getSubcategory()->asArray()->all();
        $subcategory8 = Category::find()->where(["id" => 8])->one()->getSubcategory()->asArray()->all();

        if ($model->load(\Yii::$app->request->post()) && $model->save()) {
            \Yii::$app->getSession()->setFlash('success', \Yii::t('user', 'Компетенция успешно изменена'));
            return $this->redirect(['competence']);
        }

        return $this->render('update_competence', [
            'model' => $model, 'subcategory1' => $subcategory1,
            'subcategory2' => $subcategory2,
            'subcategory3' => $subcategory3,
            'subcategory4' => $subcategory4,
            'subcategory5' => $subcategory5,
            'subcategory6' => $subcategory6,
            'subcategory7' => $subcategory7,
            'subcategory8' => $subcategory8,
            'category' => $category
        ]);
    }

    /**

    protected function findModelCompetence($id)
    {
        if (($model = ConsSubcategory::findOne($id)) !== null) {
            return $model;
        }

        throw new NotFoundHttpException('The requested page does not exist.');
    }
