When I installed the dimmer, listed on your list of compatible dimmers for your LED replacement kit, it would not turn the lights on. I do not know if the five lights are wired in series, but suspect they are. The original single pole switch will work with your LED lights.
Normally plugging 5 LED light bulbs should not manifest any problems if your dimmer is listed as being compatible.
Have you tried troubleshooting with other type of bulbs ?
There might be an issue with the installation.
