Why do i see uncommitted changes in my new branch

Summary:

Trying to establish the correct way of handling multiple page changes in an environment. Hav e created a workspace with a single branch but when i create a new branch it appears to have my changes from my first branch

Content (please ensure you mask any confidential information):

Have created 1 project , 1 workspace with a branch from main entitled TransferPage.

Have edited the My Team>Transfer Page in Visual Studio Builder (Express mode) and have created a simple rule and made a field visible. I have not published this change. Exit VSB

Open the My Client Groups> Hire an employee and edit the page in Visual Studio Builder (Express mode) . Switch branch and create a new branch based on local main ( have also tried with remote main). Chose not to commit changes ( i understand this would take my changes from the transfer page).
