Date information is not reflected properly for Studio projects in Windows Explorer...is it normal?

Dear Studio 2017 users,

I am not sure if this is related to Windows settings or it's related to Studio, but I have noticed the "Date modified" column in Windows Explorer does not have the correct date information.  When each project is in folder view in Explorer, the date shown in Date modified is the date when project was created, not the date the project was last modified.  Is there a way to change this so that the "date modified" displays the correct information?

Thank you.
