Is the number of tags limited?

Today, I wanted to add a new tag, and that would be the eleventh. It is added in the flashcard but it isn’t listed if I open the tags.

Later added:
the question is solved. The solution is that the system reacts a little slower. After a while, the tag is there.

Another point seems to be important for importing. There shouldn’t be a point included in this line, otherwise the whole term will not be fully added.

@Irene777 - Glad to hear this is working now. As you point out, punctuation won’t be included in any LingQ that you save. This is because punctuation causes formatting issues.

Thank you very much for all your help.
Could you see my other question, too “Again a problem”?
Perhaps you can help me there.
