Entire Test suite gets deleted when I try to delete a coloumn in datasoure by keybord delete button

I am using ready API 1.3.1.

See wired behaviour and lost my lot of work two times:(

Ready API will delete the entire test suite when user select a column name in DataSource and hit Keyboard Delete key. Although it gives the right alert message but I don’t expect it to alert me for entire test suite deletion when I wanted to delete just one column in data-source. You try to select the exact coulum name in datasource (grid) and hit delete button its ask to delete the test suite.

Should be considered as a bug in ReadyAPI?

Thanks
