Rewrite results output creates 2 links for one for one rewritten custom text field
When rewriting a field into a custom link you have to make sure that the tokens used for the link text aren't formatted as links, because links can't be nested one into the other. 

Edit the field settings for the fields corresponding to {{ field_tool_manufacturer }} and {{ title }} and make sure their Formatter option is set to Plain text, or that the option to "link this field to content" is not checked.

Most field settings will be applied to the token in the Rewrite field option, so you have to control the output yourself.   

You can test what the field output is by simply viewing the field without any Rewrite options, and if you see the field output as plain text, and not a link, you can proceed to set up the Rewrite options.
