Confliction with Calculated Fields Form

Hi,
Firstly congrats on producing such a great plugin. I have been using it for 2 years now and it has been awesome.
Secondly, there is a confliction between your plugin and the Calculated Fields Form plugin when it is being used with the user registration add on in the developer version. Clean Talk when enabled causes false error messages during the registration regarding the user login already being in use. However, it does not block the eventual user registration. I have spoken to CFF team and they say that this is an issue with your plugin. I can get around it but it would be great if they both worked nicely together. When I remove all protection by Clean Talk or deactivate the plugin the form works ok so it is definitely being caused by Clean Talk.
If you need any more info please let me know. I have a staging site where you can see the issue.
