What does a red mark on the project folder signify?

Hi experts,

I created a new project in HANA version 1.0.53 and added csv, hdbtable and many other files.

When I activated each of these files, I got some errors initially but then I sorted them out.

Now, all my files inside my project are active (orange cylinder) but still there's a red box on my project folder.

When I right click the project, commit, check and activate options are disabled.

Am able to select only "resolve" but even that doesn't seem to resolve anything!

All the files are available on the repository as well.

Am not sure what the "red box" on my project folder signifies and how to fix it.

Regards,

Bala.
