I have to come back to this problem again.
The answer was that this is not a Locus problem but a BRouter problem.
What's the problem: if there are overlapping sections on the route and there is a turn, the Locus navigation does not see it and there is no message (Picture_2_LM).
I have been investigating the topic for almost a month.
I did the routes on the Locus Planner Web - for all the above situations the Locus failed - there was no news.
On the forums I found people who have already notified you about this error,
but it turns out that they too were left unanswered.
So what about this problem?
No turn message in navigation
it is increasingly common for the navigation to not provide turn announcements.
I am giving an extreme example, because the turn is 90 degrees from the route I drove on 10/07/2022, and it was already the 2nd turn, where there was no message. But there are also messages about a turn when it is not there.
