Leopardmon

Q:Do I have to activate this card's [When Evolving] effect?

A:No, you can choose not to use it.

Q:Can I use this card's [When Digivolving] effect on a Level 4 Digimon card that's part of this card's digivolution cards?

A:Yes, you can.

Q:Will this card's [Your Turn] effect result in my Level 4 Digimon with losing when Digivolving to Level 5 or above?

A:Yes, because the effect is only active during [Your Turn], the moment the Digimon becomes Level 5 or above, the effect no longer applies to the Digimon, and it will lose .
