There are also some other things that I notice. 

1. The start button in the "Custom slide show" window run the entire slide show not the selected one till you tick the "Use custom slide show" button which will make it the default slide show that is run from the main window as well
2. "Use custom slide show" doesn't get activated from the first time, I have to reopen the window and tick it again.

When reopened in LO and MSO custom show is there and it runs in MSO. 
I set Verified, thanks.
Comment 7 Timur 2021-06-01 08:29:16 UTC
Upon further testing, seems that there's something wrong here.
1. open PPTX attachment 172523 [details] which is Custom slide show from MSO
see that custom SS are imported and run OK (bug 131390)
2. save as PPTX in LO 
3. reopen in MSO and see that custom SS runs OK
4. reopen in LO and see that custom SS doesn't run (with "Use custom SS" and "Start")
Comment 8 Timur 2021-06-02 07:04:25 UTC
I guess I was wrong. 
This is not about PPTX but Impress doesn't run custom SS on 1st run, bug 142595.
