Only last commiter can see the files. How every members of the project can see all files?

Hello

We are three members of one project and I am the owner of this project. Other two members have a developer role. We found that we only can see the last commiter’s file in gitlab where the other two members are not able to see their committed files.

Only last committer can see the files in gitlab. We are using private reposity there. How to solve this issue so that everyone can see all the files who are the members of this project??

Regards,
Prakash

Please anyone help.
