Is it doing that for all the strings/tuning notes? I would double check using an online tuner. Your tuner battery could be getting low if it’s wrong?

Here is an A-note 440 Hz, you can tune your 5th string to match this, and then fret your 5th fret 6th string to match the correct A-note open 5th string.

Nothing wrong with tuning all the strings down a half tone, makes it easier to play. You can always put a capo on the first fret to match standard open tuning if you’re playing with others.
