Strange curly patterns on my Apple Mint leaves

Hello, I have been having problems with my Apple Mint plant.
I love the smell of this Apple Mint so I am hoping there is some way to save it :(

:idea: As far as I can see, there are no visible insects on the plant. I have had this Apple Mint growing near some other mints and they have not shown any similar problems.
At the moment all I can do is cut off the leaves as they start showing signs.

What is causing this ?
Please help me ! Thanks very much in advance :o

I'm sorry I didn't see this post until today.
Did you find out what causes the patterns? I'm pretty sure this is from a leaf miner. It's a fly maggot that lives between the top layer and the bottom layer of the leaf. Your best bet is to systematically pluck the affected leaves and destroy them -- preferably by freezing them -- before throwing them away. The larvae emerge and pupate in the soil, so you want to get rid of them while they're still in the leaf. Sticky traps and soapy water dish traps mentioned on 2nd or 3rd page of this thread https://www.helpfulgardener.com/forum/viewtopic.php?t=9591&highlight=
might help to catch the adults.
Good luck.
