Release Date sets arbitrary values

I ran into some problems with the “Release Date” feature:

1. When I save a post as a draft without scheduling, sometimes the “Release Date” is remained empty, but sometimes it it fills up only when I click “Schedule” in the WordPress editor view. The documentation in the plugin page says only save as a draft and exit to the control panel. This is confusing and inconsistent.

2. The value I see eventually in Release Date is about 8-10 minutes from the time I click the schedule button. I think it’s always a 10 minute multiple, like :00, :10 and so on. When I check the date in the post’s Quick Edit view, I see the time and date that I have set. When I try to re-schedule, the Release Date won’t update. HELP!

I can’t understand the way Release Date works. Is that a documentation problem or is it a technical problem on my side?

I run a Multisite Install with Elementor. Does the plugin even support Multisite?

Thanks in advance (I schedule them).
