Condensing gliss. issue

Hello, when condensing the first violins (div. in 3), which all gliss. at the exact same time, the gliss. disappears in the condensed score. Is there any reason why? The second violins (div. in 2) condense their gliss. just fine. Thanks!

Have you tried copying the first violin 1’s passage to the other two divisi, and then re-pitching the notes with Lock Duration? If the gliss isn’t in exactly the same place rhythmically it may not condense correctly for all three players. If that doesn’t work, I’m not sure what else to do - occasionally weird things happen when condensing.
