When you disable [ Clip Auto Extend ] That is no problem there. But when you need to merge the clips it adds keyframes, it adds unwanted animations, it also includes invisible keyframes (pose from avatar changes but nothing visual on the timeline), it basically does not reproduce the existing animation into one clip. It's a mess.
Included is 2 zip files one shows before merged clips the other shows merged clip result.
I saved my project as I went along. Incrementing the file name. BTW feature an automatic incrementing file number please.
Start:
I make 3 keyframes, @1, 50, 100, When I selected all keyframes and chose Merge Clips, it doesn't change the animation but creates 7 keyframes 2 at the beginning 3 in the middle and 2 at the end, ideally there should be only 3 and you can't merge the middle 3 keyframes or merge the 2 at the end or it creates an unwanted outcome.
When I split the merged clip in the middle then move them apart it works as it should.
When I split the second merged clip the entire clip fills with keyframes, a very unwanted result. In other projects if you have a clip that is 300 frames long or more and it fills with keyframes every action slows to a crawl as it is overwhelmed.
You guys still have work to do to improve this.

Using ICiClone7.5_20190731.1 on my first try, upon opening another file (one was opened already) crashed my GPU, all 3 monitors when dark, luckily the GPU rest itself and all 3 monitors came back.
Scary so far.
