Can confirm and replicate the issue everytime including on the most recent build #1a6e658.

Steps to reproduce

After parking at gate with engines still running and ADIRS aligned:

1. APU bleed on
2. Engine mode normal
3. Engine master switches off
4. Fuel pumps off
5. Beacon
6. External power on
7. ADIRS off

ECAM will display warning and master warning will trigger.

Seems to be directly related to ADIRS being switched off after engine masters off with engine mode normal.
