Please @Gina1960 help me i won t disturb you anymore

Ha Franci you can ask, I may not always know the answer!!
It kind of looks like that leaf just melted.
The plant, how long have you had it? And chance it was exposed to heat or cold?
I would remove that leaf, very gently and expose the apical meristem (the growing tip) to see what it looks like. If there has been some sort of insult where the tip has been damaged, you may need to cut back to the last node.

Thanks a lot for suggestion, i can t understand i ve some mosquito of fruit but few, maybe is their fault. i had sensor wich monitor light humi and temp near plant and was all as usual, also other 5 aroids near are developing new leaves and are ok, and other too Thanks for kind help Gina
