bug orbital effect duration

hello, on my skills' config, i create a skill that cast a orbital effect:

- orbital{onTick=Healings-Tick;points=13;interval=0.01;duration=15;charges=1;r=1;rz=-0.3;ry=8;oy=0.6;hp=false;hnp=false} @Target{ignore=monsters}

but even in the end of the skill, the orbital doesn't end, it just keep going

i tried it with the Latest Development Version: v4.11.-3520 on minecraft 1.15.2
