I often hear these mistakes made by German speakers who are learning English.
They say: Is this the actual presentation or the old one?
The problem here is the word actual. It is a mistranslation of the German word ‘aktuell’. What you mean to say is ‘current’.
Correction: Is this the current presentation or the old one?
Alternatively we can say:
Is this the latest version of the presentation?
Is this the most up-to-date version of the presentation?
Have fun learning English!
