I have created a website with two vertical Spy menus (left side of page) but for some unknown reason when you select the sub menu the following issues occur.

Sub menu laps over the main menu when selected but only to the left slightly it also appears slighty above the main menu only slightly.

I want to see the main menu and the sub menu appear all at the same height

The text also changes size smaller. when selected by the mouse.

any suggestions on how to improve this thank you.
