[GreenKeys] 1/6 the strikers on typebar carriage striking at the same time

[Windows XD]

Dear Greenkeys community,

When I simulate a striking motion on my model 19 (same as 15) typebar
carriage, almost 1/6 of the strikers go up that shouldn’t (see attached
image, only the one highlighted in green should be going up.)
This happened after I removed and regreased the strikers. It appears to be
the arm (see image) is caught on several strikers it shouldn’t be. What
should I do to fix this?

Any help would be appreciated!!

P.S. 4 keys have been removed, the springs were broken, this is temporary
so you don’t need to point it out.
