Bugs in content types

Hello,

I have two problems with speaking words set (desktop, Chrome, Wordpress)

1. After creating a lot of questions I realized that only 1 or 2 were saved (even if I clicked update/save button on the right after everything was done) it happened to every content that I've created yesterday. But it seems to work when I click save after creating each question so I should be able to finish it, so we can consider it a minor problem

My timeline suddenly stopped displaying. In its place I now see a white box stating: Missing mandatory data - not able to draw the timeline. Please open this H5P in the editor, and make the necessary changes. Yes, I worked on timeline recently and could have inadvertently elbowed the keyboard--but I have had this timeline for years and nothing like this has ever happened.

Troubleshooting: Copied timeline, created a new timeline, pasted, got the same error.

The timeline is displayed at https://hebrewlion.com/learn.

Hi Not sure if this is a bug or not but I have been trying all day to fix this but its not making much sense:
