after Update Problems with opened active branch

Hello, after updating this pluginn is not working anymr fine.

If the user press our product, I want that the active branch is open and the level coloured in blue.

Here is working fine, because this page is included in menu.

If you choose a product page like this everything is close. I guess that problem is because not every product contain in menu.

How I can fix it? Thanks.
