File size error

I have a problem when using any synchronizing software to sync a folder encrypted by Boxcryptor and available on OneDrive with the option "Files on-demand" selected.

Files on-demand option for OneDrive removes local copies of the files and replaces them with a place holder having same properties and zero size on disk.

However, when the placeholder is for an encrypted file using Boxcryptor the file size is reported incorrectly.

File encrypted with Boxcryptor (inside Boxcryptor folder i.e. double clicking will open the decrypted file)
Placeholder size: 9,206,336 bytes (Zero bytes on disk) Notice the size of the place holder is 9bytes more than what it is supposed to be
Actual file size: 9,206,327 bytes (9.2 MB on disk)

Same File unencrypted: (i.e file placed in OneDrive folder)
Placeholder size: 9,206,327 bytes (Zero bytes on disk)
Actual file size: 9,206,327 bytes (9.2 MB on disk)

Adding to the above, I tried the same with google file stream and the same problem happened. the file size is not reported correctly which makes it impossible to synchronize the folder correctly.
