Learn Tibetan does not display SAVE button when trying to Ignore a word or all words is used. For example, when I try to ignore all the numbers in Level 13 (want to come back later on numbers, there is no Save button display at the bottom of the page. I have tried making the page fonts larger and smaller to no avail. I can ignore words individually when they arise as content but that is a lot slower. So this is no big deal but a nice to have feature. Thanks.
