Premiere cant replace "interview" footage, clips in the timeline stay offline!

[#1]

For a film that I made in Premiere Pro CC 2018 I used 4k material, that I transcoded into 1080p and for better playback in Premiere I made Proxys of them.

The big problem is, that I deleted my source material --> the 1080p clips and my proxys. I still have the original 4k material from the camera. So I have a complete "offline" Timeline.

To get my film working again, I made new 1080p clips from the 4k material. Now the 1080p clips are pro res 422 HQ, so I dont need Proxys.

When Iam replacing a single offline clip, that is used only one time in my timeline, everything is fine and I have an image, the replacement is sucessfull.

But now the big big problem: When Iam replacing a clip from an interview I made, from which I used for example 4 different parts (in and outs) of the interview in the timeline, Premiere cant replace the offline clips in the timeline. They are still offline. Any help?
