1H-NMR: acetic acid-d4 solvent peaks off from the expected value

Hello there.

After running an 1H-NMR experiment I observed the acetic acid-d4 solvent peaks at 11.54 and 21.16 ppm (off the expected values by ~9 ppm to lower fields).

Is it possible that the lock was made onto the wrong deuterium acetic acid-d4 signal?

Please, advice.
