Hello. Yes the trial version is not updated on a frequent basis and this bug was not found until after the trial version was created. This was also brought up here:
Dynamic Forms Trial SQL Bug
The main version of the module does function properly however the trial version still has not been patched with the same patch. If you would like you can demo/test the non-trial version before purchase on www.betasprings.com as its not running the trial there.
Thanks,
Chad
