While importing a new lesson, I noticed that the level dropdown refuses to accept level one chooses. I have seen the same error on other dropdowns, like the number of lines in a filter of the vocab list. It looks like the number of lines does increase, but the box still shows the old number of lines. The same goes for the level. I can choose intermediate 1, but it stays on the word level. The lesson does get the chosen level.

It looks like a presentation issue in dropdown boxes.

I use the Firefox browser.
