Damage on new leaf

[beckky]

Hello, good evening! I am new here and I am looking forward to learn how to care for my orchids with your help 😊 I am not new at having orchids, I had them in the past, but these are really giving me a hard time.
I would like to know your opinion about this one. I bought it earlier this year, in full bloom and it stayed like that until May. It looked great and healthy. In the meantime I moved, and the problems started. I was super excited to see a new leaf growing, but at the same time I noticed a bumpy texture on some leaves as well as in the new leaf. Right now the bumpy texture improved (edema?) but the poor leaf looks terrible. I took some photos to a nursery but they couldn't help me to identify what was wrong.
If you could give my any hints I would be super thankful 💕
