Old power dimmer doesn't work with dimmable LED

Dear all, I try to change old halogen lights by dimmable LEDs on K5002, K8024.
It doesn’t work (flickering, impossible to deactivate,…) but if I put a simple bulb lamp in parallel, it works !
Do you have a better solution ? Thanks for your help !

I’m not sure but it seems that the LED bulbs would not provide a big enough load for either of the units you have. These have been around a lot longer then LED bulbs.
