when i select a word to add into my lings, sometimes subsequent words are also lingqed with the same definition, i usually delete the information on the word, and i add all the words one by one again to the known words or lingqed words. but this is a shortcut, and it is annoying sometimes.
Hi! This can happen sometimes when you select a hint for one word, then quickly click on another word. What I recommend is waiting just a bit longer for the site to respond when you click on a hint in the blue pane. If you find that this happens, you can also just refresh the page and it will be fixed.
thank you very much
