playsound with resourcepacks -> infinite hearing range

I have a resourcepack with some custom sounds for my vanilla server, which worked perfectly until the 1.14. Since then all the sounds out of the resourcepack, which doesn't replace already existing minecraft sounds, are played with infinite range and no positioning at a certain loaction. When i play a sound with  "@a master 0 0 0 1" , then everybody on the server hears the sound everywhere in full volume even if they change their location. If i try this with exact the same command but with a original minecraft sound, it is only hearable the usual 16 blocks and can be locatet (sound comes from right or left). I created a new sound for "entity.minecart.inside" and it works as it should. The Problem appears only with completly new sound events, which Minecraft "doesn't know". As you can see in the screenshots, i tested it with 3 sounds: "nichteinsteigen" as a new sound with this problem, "entity.minecart.inside" which is a new sound for an existing sound event, and "entity.ender_dragon.growl" which is the original sound.
