Magento offline custom Payment method with drop down list

Question

I started working on magento2 since 2 months, i have payment method which was working before and suddenly it stopped. i could not able to figure out the problem.

Please find the zip file. https://drive.google.com/open?id=12IpO3fh-8MfJnMTwHlz26vY7puy5biEg

I tried to copy the module and used in new installed magento but in front-end it displayed the drop down list but order is not getting completed.

enter image description here

This is screen shot of back end which is not Listing out the drop down list. When I tried place order from magento backed, it is not saving the "XYZ" selected value in Database.

Back end does't display drop down values
