Watermarks are not placed on rendition

hello,
I have problems with placing the watermarks on my images.

1st problem is that when I configured watermark firstly and configured rendition template later and lastly choose proper watermark the watermark wasn;t applied.

2nd problem is when I am trying to apply it manually via the DAM panel under Renditions and set the proper watermark template the new renditions are generated, but on new rendition there are no watermark.

I am using text watermark with Courier bold font.

Watermarks are applied manually. You create a renditions and apply the
watermark. If your OS doesn’t have courier installed it will fail. Did you
try it with a different font? Did you try it with an image?
