On a serious note, none of the versions I've used work.
I've accidentally found a working solution.
First I flashed xposed-v88.2-sdk24-arm64.zip, then XposedInstaller_by_dvdandroid_04_08_17.apk and had the same issue as you - all seems to be OK, but no module could be activated.
Then I have flashed xposed-v88.2-sdk24-topjohnwu.zip which is Systemless module. No changes though.
Then I decided to uninstall xposed, so I have flashed xposed-uninstaller-20160829-arm64.zip.
The xposed status was changed to Systemless, as on screenshot and now modules got activated and working.
