[solved] Apparent Bug v6.1

I guess you get the same result with version 5.6.3

There are no room for 3 columns at the right side, so TLB expand menu to the left. So if you change the columns number to 2 menu will expand to the right. Also check the options "Menu Position" in Customize menu (for submenu with episodes), set both "Docking point" and "Menu align" to the "default".
