I found a strange bug

Good afternoon. Unfortunately, the laws of my country on personal data prohibit the transfer of sensitive data to third parties. I have a large website with thousands of users. It sounds absurd, but it’s true. But I checked the _wfstatus table and I see the results of the last scan. At the same time, I do not see the scan progress log on the scan page. I cleaned the cache, cleaned the browser cache, went into the admin area of another browser, the problem persists. The result of the last scan log is displayed for 24 hours and then cleared. But he doesn’t find any problems with viruses. I checked with other antiviruses – the site is not infected. There are no problems on similar sites on the same hosting. Why is this happening? The only difference from other sites is that there are several thousand users on the site (not bots, but real users). I turned off password verification during scanning, but it did not solve the problem. What can be done in this situation and how critical is it?

Good afternoon. I see only 100 rows in the _wfstatus table.

I will complete the answer. There are 500 entries in this table immediately after scanning, and after 24 hours there are 100 entries, but the results are not visible on the scan page in the wordpress plugin.
