Hello Hemanth sai,
If you accidentally opened the correction window for SSC CHSL, but didn't actually change or submit the correction form, then your original (first) application is still valid. The system is showing you two attempts because:
As long as you do not submit any correction, your first application will not be rejected. It will be included for the exam. You just have to ensure your original application is "successfully submitted" with no corrections submitted.
