Half the Egyptian coins issued AH 1335 are listed with Gregorian dates instead of Hijri dates [решено]

Searching for the year 1335 finds six coins, but searching for Gregorian dates 1916-1917 finds all twelve. I checked several and the year lines are locked so I can't submit a useful change request.

Correct :

Need to be converted to the Hijri calendar.
