Windows Permissions code: confusing answers while fetching the ACEs

Question

While implementing a piece code to fetch the ACE's for owner and group, I am using this code as an inspiration.

To test this code, I created a file in a folder.

In an elevated command prompt, I run the app (exe created from above code) with file name as an input and see the output which is as below

C:\>C:\Users\user\Documents\VS2017\Project4\Debug\Project4.exe C:\Deny\file.txt
file:C:\Deny\file.txt
Owner: DOMAIN/user
Group: DOMAIN/user

::DACL::
GetAce Output : 1
SID: DOMAIN/user
ACE: mask:2032127 sidStart:1281 header type=1 header flags=0
 DELETE
 FILE_GENERIC_READ
 FILE_GENERIC_WRITE
 FILE_GENERIC_EXECUTE
 READ_CONTROL
 WRITE_DAC
 WRITE_OWNER
 SYNCHRONIZE

::SECURITY_DESCRIPTOR_CONTROL::
 SE_DACL_PRESENT
 SE_DACL_PROTECTED
 SE_SELF_RELATIVE

I right click the same file and in the security settings, I deny all the permissions to the file for the same user.

I again run the app on this file and I still get the same output

C:\>C:\Users\user\Documents\VS2017\Project4\Debug\Project4.exe C:\Deny\file.txt
file:C:\Deny\file.txt
Owner: DOMAIN/user
Group: DOMAIN/user

::DACL::
GetAce Output : 1
SID: DOMAIN/user
ACE: mask:2032127 sidStart:1281 header type=1 header flags=0
 DELETE
 FILE_GENERIC_READ
 FILE_GENERIC_WRITE
 FILE_GENERIC_EXECUTE
 READ_CONTROL
 WRITE_DAC
 WRITE_OWNER
 SYNCHRONIZE

::SECURITY_DESCRIPTOR_CONTROL::
 SE_DACL_PRESENT
 SE_DACL_PROTECTED
 SE_SELF_RELATIVE

Am I missing something ? I tried to understand this code and I could not figure out any obvious mistakes.
