Yes, it has been fixed in Nik Collection by DxO. As you are likely aware, this was an issue that arose with the previous version of the Nik Collection. When our developers began working on a fix for this compatibility, there was no way to know how much time it would take to create a fix. Due to the amount of time it took, and the cost to fix this issue, we will not be fixing this issue in Nik Collection 2018 by DxO unfortunately.
For more details, please read the release note of Nik Collection.
