When using Matching Objects filter within Automation Graph Rules, unexpected redirect occurs

[xmacan]

Describe the bug
If I use this filter and change and try to change object number, I'm redirected to another page

To Reproduce
Steps to reproduce the behavior:

1. Go to automation - > graph rules, choose one
2. Enable "Show matching objects"
3. Use filter "Matching objects" (for example insert any hostname from matching objects)
4. in the same filter try to change Objects from default to any number
5. You will be redirected to Automation -> Graph rules

Expected behavior
After step 4 I'm expecting stay in the same page and change only filter result. But I'm redirected to list of Graph rules and data from Matching object filter are filled in this form.
