Checked the cause of why the billable checkbox is not working when tested, as per checking the billable checked/unchecked data is saved correctly, and the checkbox is working but it is now showing the correct data when editing the activity. Modified the script and added conditions for the checkbox based on its value saved from the database, and added a function to set a value based if the checkbox check or uncheck, 1 for checked and 0 for unchecked. Tested the changes, and as per testing, the checkbox is displaying the correct data on what is saved in the database, but for saving the checked checkbox when it is edited from uncheck, it is now saving the correct value, modified the function for changing the approach and tested is again, as per testing, it is now ok. Pulled the changes from git again, then committed and pushed my changes, and my commits reflected on git.
