Browsing the NavigraphDB.dat shows the data is outdated:
sqlite> SELECT * FROM tbl_pa_airports WHERE airport_identifier=‘OEKK’;

OEKK was renamed OESD in cycle 2508.
Or better yet, after reading the format documentation:
sqlite> SELECT * FROM tbl_hdr_header;

P.S. the FMS Data Manager download does appear to serve 2508:
sqlite> SELECT * FROM tbl_hdr_header;

Also tried clearing cache (again) and tried a third browser, manual downloads still seems to be serving archive tds_gtnxi_native_2508.zip with SHA-256 sum 32d0f8e0c4367c0e57d88c822647fe5510ce6a3f4c3410f03e0c54aa50a78bc1
