Process chain unable to delete PSA requests

I am running into a very unique situation in BW 7.4 where the Process Chain event is unable to delete PSA requests only for certain standard 3.x DataSources that start with 80. These DataSources are loaded through InfoPackage groups.

I can manually delete these requests from the 3.x DataSources but not through the process chain event. Interestingly other 3.x Custom DataSources (that begin with 8Z) have no such issue with PSA request deletions through Process Chain.

Has anyone else run into this issue. I do not receive any error message from the process chain, the selection does not seem to pick any requests associated with these DataSources.

I checked this blog Change Log and PSA Variant does not delete the Change Log and PSA requests - Business Intelligence (BusinessObjects) - S…

but note 1385479 is already implemented.

I am uploading a picture with this post, there are more 100 requests that are older than 5 days in 80SD_C04 but no deletion occurs in the process chain.

Any help would be appreciated.
