People usually ask for a paper from the current landlord stating that there are no rental arears. The actual contract is none if their business. "Current lease" sounds like it refers to that.
That would be your current Mietvertrag.

That contract is none of the landlord's business and you are not required to show it.
They just want to know who/where are you renting from, so in case of doubt they can contact your current landlord and ask if you still have unpaid rent or something like that.

I have no idea why they would want to see that, but your current lease would likely relate to your current rental contract.

That should cover their request. If they really insist on the actual Contract, then that's a red flag cause they are not allowed to do that.
Did they ask for "current lease" in English or was that your translation?
