When negative delay is applied, some notes are not played in the correct timing

[sunnych]

I applied the same negative delay (-440ms) to everything in the expression map. I found some notes are holding forever and destroying the whole playback. In further investigation, I found that some notes are not playing at the right timing. In key editor, playing techniques among these problematic meters are also overlapping which it should not. Below is an example (the staff is in treble clef):

In the score, the two slurs are not overlapping, but the “legato” playing techniques are overlapping.

Playback:

In the audio, it can be heard that the C# note is played at an 8th note earlier than it should, where it should be an 8th rest.

1. Is there a question here?
2. If there is, and you want someone’s insight, you will need to upload a project

As the title and the body mentioned, the playback is not following the notation as it should. This is a bug report. I do not understand if there is any question to my question.

Unfortunately, I could not upload the project. If you mean this is not resolvable based on my provided information, I will leave this and turn around.

In additional to the reported issue, I found another similar issue which is more obvious. I am not going to start another post.

Besides playback, even the starting position of the highlighted note in the key editor is incorrect. The expected result is that, a negative delay should be applied to the note, as the expression map imposes everything with a negative delay.

I first thought it is an issue of playback override, but apparently it could not be reset, and there seems to be no override.
