Vegas Pro 14 - Match Event Length not working sometimes

[queensoft]

I have a video with at least 200 ProType Titler texts.
All are created using copy/paste (create new copy, NOT reference to original media)
All use same exact settings (font, size, alignment, layout > selection > create animation....)
For a few of them (random?), the Match Event Length is not working properly.
The event length is the same as selected length (lower right corner).
But the animation the animation repeats itself, it's short about 0.4 - 0.6 seconds.
If I manually add a bit of time, everything is OK.
Check attached screenshot.

Thank you.
