Accordeon menu expands randomly with Hikashop

I can't figure out why the menu expands itself to some random location. For example, clicking on "Checkout" will expand much of the hiearchy, several levels.
Is there a way to control this behavior?

Hi
the first work to start a discussion would be "hello" ...
then give me your url, but if the menu expand then there is a link that is active in the tree of your page
CEd

url received
pleas try to disable the sef to compare the url between "chackout" and "Work & Construction Zone" because this one is active.May be an Itemid conflict
you are using a patch ecommerce for the menu ?

your urls are
checkout :

index.php?option=com_hikashop&ctrl=product&task=listing&Itemid=471

accordeon category :

index.php?option=com_hikashop&ctrl=category&task=listing&cid=247&name=work-construction-zone&Itemid=530

I wonder why your checkout page points to a product page (option=com_hikashop&ctrl=product)
please try with another template than Art...., just test the native beez_20
also try to create another link to the checkout page.
The problem for me is that the checkout page points to a product which seems be linked to the category "work-construction-zone" so this one becomes active
