What to do if you stand after the second rak'ah of Tarabeeh prayer 2334171165

One day in the last Ramadan, when I was leading the Tarabeeh, I forgot not to sit after the 2nd rak'ah. When I went to prostrate after reciting the Qur'an, I remembered that I had recited three rak'ats. Without seeing any change, I completed another rak'at and completed four rak'ats and finished the prayer with Sahujijdar. After the salutation, our Imam said, the prayer has not taken place. These four rak'ahs must be recited again. According to him, these four rak'ats are recited again. But later when he asked another scholar, he said that the prayer was over. There was no need to read a second time. So now I want to know from the lord, what is the right thing here? In this case, what is the correct method of performing the prayer? 8858483784
