You already have an app under review

I have created a project for controlling home appliances with Arduino board. After completion of that project i placed a request for monetization approval. It’s had been 3 months under review. So I thought for delete that project because there was no hope for that project to get approval and so I have deleted that project. But now, for other projects in monetization tap it showing that “You already have an app under review”. I have deleted that project from my kodular account. I am not able to place any request for monetization. Help please.!!
