Question about Smart Nav and Card Design

Hey Guys

Does anyone know the reason or have a solution for the following problem. I’m using SMART NAV in a navigation bar with the respective List Item customized through class. It happens that, when I go over the links (buttons), the border defined in the Class Editor is lost. Does anyone know the solution for this? The strange thing is that, when I disable the smartnav Class, the problem no longer exists. There is an incompatibility here between SMART NAV and Class elements.
Another problem I’m having is when using Card Design in bootstrap 5, the texts are all underlined. When I use it with bootstrap 4 this no longer happens.

If anyone has information about these bugs, I would appreciate it if you shared it.
