Sharpen AI 2.05 Plugin - Affinity Photo

Since last year I´m using Affinity Photo with Denoise AI Plugin without any Problems.

Today I installed Sharpen AI Plugin. It works but there is the following problem: The preview in the plugin shows the correct ( same as standalone ) sharpening effect. After applying and back in Affinity Photo, the sharpening effect ist ( much ) more less than in plugin preview.

Using the standalone version, every thing ist ok.

Some ideas?

I investigated a little bit more. Even in standalone the saved file is not that sharp as the preview. It seems, the preview rendering algorithm compromises too much for speed than for quality. Wysiwyg would be desirable.
