[Vuejs]-Vue router-link changes style of elements

From the code, I could not derive, where exactly the problem lies. The router links look fine. Vue generally tries to prevent content from loading, if it has been loaded before to improve performance. This could be the case here, but it should be fixable.
I’d use Vue Devtools instead of the normal dev tools. This way you get further insights and you’ve got that already installed. If you could share a screenshot of the particular element, I could try to analyze the problem further! 🙂
