Can't Lingq a sentence

I have noticed that when i lingq a sentence comprising of diferent lingqs, it sometimes doesn’t work. I cant make a lingq. Sometimes when it is posible it will disapear when i go back to the lesson later. This is something thats been going on for a long time, but since it’s only at certain times i have ignored it until now.

Hi Patrick,
Are there any shorter phrases saved within the phrase you are trying to LingQ? If so, if you delete these shorter phrases then try saving this longer phrase again does it display properly?

i tried it and now it works. But i dont want to lose the shorter phrase.
