TableLayoutPanel displays vertical scroll

I have TableLayoutPanel for dynamic creation of controls with AutoScroll = true. It's work fine when I add new controls. But when I remove and all controls are visible, vertical scroll is visible. Some screenshots here:

Expected/correct scroll visibility:

Incorrect visibility:

Any ideas?

Update: Here is some code

tableLayoutPanel1.SuspendLayout();
tableLayoutPanel1.RowCount = 0;
tableLayoutPanel1.RowStyles.Clear();
tableLayoutPanel1.AutoScroll = true;
tableLayoutPanel1.Padding = new Padding(0, 0, SystemInformation.VerticalScrollBarWidth, 0);
foreach (var item in objects)
{
     tableLayoutPanel1.RowCount++;
     tableLayoutPanel1.RowStyles.Add(new RowStyle(SizeType.AutoSize));
     tableLayoutPanel1.Controls.Add(CreateNewItem(item));
 }

 tableLayoutPanel1.RowCount++;
 tableLayoutPanel1.RowStyles.Add(new RowStyle(SizeType.AutoSize));
 tableLayoutPanel1.Controls.Add(CreateAddButton());

 tableLayoutPanel1.ResumeLayout();

and code for deleting

tableLayoutPanel1.SuspendLayout();
tableLayoutPanel1.Controls.Remove(item);
tableLayoutPanel1.RowStyles.RemoveAt(0);
tableLayoutPanel1.RowCount--;
tableLayoutPanel1.ResumeLayout();

AutoSize is true, AutoSizeMode is GrowAndShrink
