If statements clearing controls from panels by themsemselves

Hi everyone so I haven’t done any programming for a long time so decided to a little project to get back up to speed and I’m having an issue with the methods clearing my panels and I can’t see why, I have checked all over my code and can’t see why it would clear my "PlayerPanel". From what I can tell I haven't called "PlayerPanel.Controls.Clear()" or "PlayerPanel.Controls.Refresh();" anywhere except for one button that has it as a click event. From my testing I’ve found that if a comment out the if then else in "GameDecider()" the program doesn’t clear the panel but i cant tell why . Any help is appreciated .

private void ConfirmButtonClick(object sender, EventArgs e)
    {


        if (currentPlayerDog == null)
        {

        }
        else
        {
           if(currentPlayerDog.GetChosenValue()!= "")
            {
                DrawCardButton.Visible = false;SelectedChoiceLabel.Visible = true;ConfirmButton.Visible = false; NextRoundButton.Visible = true;

                string pl1attk = currentPlayerDog.GetChosenValue();
                string pl2attk = currentComputerDog.GetComputerAttkValue(currentPlayerDog.GetChosenAttk());
                SelectedChoiceLabel.Text = "you attack with " + currentPlayerDog.GetChosenAttk() + " " + pl1attk + " | " + "Computer attacks with " + currentPlayerDog.GetChosenAttk() + " " + pl2attk;
                currentComputerDog.SetTextVisible();
