Other DVDFab logo on playback

[midwaybrit]

I am running the trial BluRay version, I am noticing that on anything I burn or rip that the DVDFab Logo comes and goes in the left corner. I can find nothing saying this is to be expected with the trial version. Is there any way I can turn this off ?
Thanks

This watermark is only present in trial mode produced backups.
