Button-labels wrong in German version

When creating a new subscription, 4K Video Downloader offers the option to chose whether one wants to download the entire channel or merely the future videos of this channel.
To have this option is great.

There are three buttons to chose from in this situation.
The right one is to cancel the creation of this subsription. Its German labelling is correct.
The left and the middle button are labelled misleadingly:

Using the left button (labelled "Abonnieren" which translates as "Subscribe") results in downloading merely the future videos of this channel.

Using the middle button (labelled "Download ist vorhanden" which translates as "Download exists") results in downloading all the old videos of this channel as well. However, the label wrongly suggests, that this button is to ignore old videos since a download of the old ones already exists.

A better labelling for the button in the middle would be "Auch alte Videos laden" which translates as "Download old videos as well". It uses exactly the same number of characters, so it does not need more space than the old labelling.

If the label of the middle button would be changed this way, the label of the left button could remain as it is, since, in the context of the middle button, its meaning would be self-evident.
