Why this pair is hard
Spanish, Japanese, Korean and Turkish have one mid front vowel and nothing lower, so 'bad' and 'bed' fall together. French and Italian have open and close e but no distinct 'cat' vowel. Hindi and Urdu map English short E onto a higher vowel, which can push 'bed' toward 'bade' and leave 'bad' unmarked.
