1. I upgraded but found that I had updated "Investors" and "city" words but now they are again visible ? I check in translations but they are correct ? How to correct it now ?

2. I had updated "STATUS" fields also in the code file you had suggested. Now after upgrade  its again back to the original state ? Shal I make the changes again in that same file ?

I have resolved the language issues. Also since I have updated the files for STATUS.

Now I found that on the front it is showing the changed ( new ) status of projects. But on the admin side it's not showing that status. Kindly check the snapshot. How to resolve it ?

I can see that STATUS is not in search filters , then what is the use of the status field ? Is there any functionality connected to STATUS or it's simply for display  purpose ?
