The yellow box looks strange

Can you please fix it? Or what am I doing wrong?

The above problem has vanished.

I have another question.
If I create an expression, I am not able to access the single words of the expression although they were blue before.
If I delete the expression, all words are white.
If I refresh the page, everything looks OK (blue again).
Is this normal?

@guineapig - Yes, that is the way it works. If you LingQ a phrase, it turns yellow so the individual words can’t stay blue. I recommend LingQing the words first. Note that if it is a common phrase you may see it in the Suggested Phrases at the bottom of the word popup.
