Problems with A/B testing in GA?

Question

Software testing

Friends, we need help, we launched an a/b test on the site. We did everything according to the instructions, there are no errors in the code and pages. The site is shown in two versions (as it should be), but the analyst writes the following:
"Note: One experimental version is not displayed in the table. More...
No sessions were registered for the following experimental version:
Variant 1"
What could be problem?

Answer 1

I had it. Didn't find a solution. Created a new experiment and it worked.
Show the experiment settings, what urls are registered for each option.
