Iron trapdoors have Trapdoor opens and Trapdoor closes, whereas wooden trapdoors have Trapdoor creaks for both.
To fix I'd recommend that wooden trapdoors also use Trapdoor closes/opens, and that subtitles for regular doors and fence gates are also changed to use such subtitles instead of vague creaks.
Please provide details in MC-98316 and someone will add it to the list.
