Hmm I can't reproduce this, I assume it's some custom CSS issue

Hi, I'm also having this issue but I believe it is caused by a single word/string longer than what would fit on the lines you specify in clamp.
If you had a string of 45 characters and specified clamp to two lines and each line only fit 20 characters it would shorten the entire string to "..." instead of 40 of the characters followed by "..."
