Some three word combinations are not lingqable

For the last months I’ve had problems creating lingqs for a few three word phrases and four word phrases [in Web; Edge]. I can’t see a pattern for when a lingq is possible and when it is not. In the picture you can see that I already created a lingq for the words “el punt i coma”: In the reader the lingq is circled and in the meanings my translation is saved. But it is not possible to move the level to (a yellow) 1, 2, 3, 4 or even “known”. For the words “punt i coma” I was able to create a lingq. Then again - in the same lesson - I could not save a lingq for “la ce trencada”. Do you know why? Is there another way to get these phases lingqed [and into the vocabulary list]?

Edit: For the word combination shown in the picture it is not possible to save a lingq neither in French, nor Italian, nor German.

Today again, I had seven three-word-phrases, that were impossible to lingq.

@Fer.weh Thanks. I asked our team to look into this.
