Fix the catalog filter (online store on Bitrix)

Problem: The filtering result shows the wrong number of products.

For example
1. The filter shows that the size of the growth parameters correspond to 16 products http://joxi.ru/vAWzO9vcBMXwq2
2. Here the result shows that there are only 13 http://joxi.ru/l2Z4x9ETRxM4Vr
3. The total number of product cards that the filter displayed for this query is 12

It seems to us that step 1 shows everything that is in the database - active, inactive, available, inaccessible.
Step 2 discarded some statuses and showed fewer products.
Step 3 showed active available. Although it is possible that in step 2 there was already the correct sampling, and here the output error.

What you need: Steps 1, 2 and 3 should show the same number of products. Products are only actively available.

About the site: Bitrix, exchange with 1C (goods come only from 1C) every hour.
The bitrix kernel has been rewritten in vue.js. Perhaps for this particular task, this fact is irrelevant. But for information, let it be.
To get acquainted with the device of the site there is its test copy. And then theres git.

Evaluation of the project - approximate, for 3-4 hours of employment of the developer. If you have a different cost estimate, specify your own in the response.
