Auction: several e-mail notifications not working

Good Day, all together!

I just recognized that bidders do not get any notification in case of an outbid by another user.
The respective mail-template "increase_auction_bid" is activated in the admin panel.

Also, sellers get no notification about new or cancelled bids.

Any ideas, how to fix this?

Thanks.
