Different episodes with same names are marked as played

Hi,
I have a problem with the podcast “Presseschau” (Presseschau - Deutschlandfunk) as the names of some (different) episodes are the same. So Antennapod marks all episodes with the same name as already played.
The download log says: “The podcast host appears to have added the same episode twice. Antennapod atttempted to repair it”.
Is there a option to prevent Antennapod from cleaning duplicates for this podcast?
Or what can I do?
I already contacted DLF and kindly asked them to use unique names, but I am not confident that this is a solution.
