Sorry you didn’t say you wanted to maintain multiple OL counted lists.
To do that would require you to introduce sections on the page to ‘contain’ each counted list.
Use a GenerateBlocks Container Block, with that block selected, in Advanced > Additional CSS class(es) add: list-container
Then change this CSS:
.entry-content {
counter-reset: list-counter;
}
to:
.entry-content .list-container {
counter-reset: list-counter;
}
Now anything inside that container will keep the count order.
So simply copy and paste the Cotnainer Block and use it for each separate list you require
