Ion-tab-button selected bug when using variable in tab attribute

Hi this is my first post here. I’ve been trying to get the tabs working for some time now. I’ve got 4 routes:
/tab/notifications
/tab/guests
/tab/profile
/tab/event/:id <-- Now here is where the problem lies

When I click on this tab button, I do get redirected without any errors, but the problem is. The button is not highlighted as active/selected.

I have a feeling I’m doing something wrong but I can’t really figure out what. Any suggestions for a solution? Thanks for the replies in advance!
