Please check if you accepted a managing request from another user (the manager's profile is listed on your profile). If that's a case, then it means that you have let your profile be managed by other user so he gets all inquiries for that profile.
You have two solutions if you don't want to let that manager get all inquiries for your profile:
You can cancel the managing for that profile by moving a cursor over three dots beside that manager on your profile and click on "Cancel managing" option and confirm. You will get all the inquiries again for that profile.
Submit a managing request to your own profile you want to manage and accept the managing request. If you don't have a manager/agency profile you can create one. After you accept the managing request you will be a manager too for that profile. It means when other user wants to communicate with the profile's owner the user has to choose which one of manager he wants to communicate with. In other words, when someone wants to stay in touch with your profile, the user has to choose a manager from dropdown list to communicate with and that doesn't necessarily mean that they will choose you. One profile can have many managers.
