Google Tag Assistant says:
Element ID or class name contains illegal character.

Rating: 4 stars

check the support tab as there is a forum post that begins with “Getting error message Element ID” where user “Never Settle” explains what to change to fix this. Basically after installing the plugin edit it and modify the plugin file that ends “/public/class-gawcc-callrail.php” and do a replace of the text “gawcc-number-swap” and change it to something like “phonenumber”. It should only appear twice in the file so replace both instances.

After changing it appears to work perfectly with Google tag assistant (chrome extension)

There’s a thread in support regarding illegal chars error in tag assistant.
Devs still havent fixed or replied. Its pretty much useless until its fixed.
