Editing advice for sharp pictures with Lr and Nik-Collection

Hello fellow AP-photographers,

i recently started uploading pictures again after a while. Most of the pictures were rejected because the main object was not sharp.

I was facing this circumstance before but i managed to find a proper workflow ( presharpening via Nik. sharpening and general edits in LR and Noise reduction in Dfine afterwards) which led to numerous accepted pictures.

Sadly im not able to create proper sharp images with this combination anymore.

Can someone help me to find a good way to edit sharp pictures with these two programms?

Thanks in advance!

David
