Hello!

I created test account number 7 - screenshot https://yadi.sk/i/nk3G-2wmizxlcQ

Then I created a test letter in the list and account number 7 is not in the list - screenshot https://yadi.sk/i/SyA8Bv9UyOEFeg

This is mistake.

But if you remove the plugin and reinstall it, then user # 7 will appear - screenshot https://yadi.sk/i/sBSFezfgkBIfYQ
