Several reports on the forum about this. FYI though, these are no spelling errors, but complete strings from another language.
The GOOD NEWS is this is user interface only, and will not appear in prints. So on the practical side the issue is not as bad as it looks.
This is an entirely different problem. I do not know if you have looked into the forum before posting and tried the proposed solutions already as there are many posts about this by now. If so, it would be nice if you mentioned, so everyone knows what does apparently not work in your case.
Thanks for your speedy response. I am now having issues with the January epub. As pictured in the screenshots the layout of some of the talks are wrong.And there seems to be a few double ups. Its in the entire month of January. The Feb epub seems to be fine.
