Drag and Drop content WILL not UPDATE

Hello, I am new here so I do not know a lot of things. Sorry.

I have created several Drag and Drop exercises. When I check them out, I find a couple of spelling errors or I want to add one more sentence, for example. I open the exercise via EDIT and make the changes. Then I tap UPDATE. When I check the exercise, my corrections are not there. When I tab EDIT again and look at the text, my changes are gone, the text is back to its former incorrect state. No matter how many times I correct it, it does not update.

 The only thing that works, is to re-create the whole thing in a wordprocessing program - perfectly, go back to H5P and delete the bad exercise and start from zero by creating a new one. This has happened several times.

I am working on an iPad.
