Formhandler: Submit-Problem (reloaded das Formular neu)

Ich habe, nachdem ich keine Zeit mehr an die unberechenbaren Bugs von Powermail verschwenden will, mir mal Formhandler angesehen (1.1.0) angesehen und ein wenig getestet.
Ist scheinbar wirklich gut gelungen.

Allerdings habe ich nachdem ich ein Radio mit Validierung in das Formular eingebaut habe das Problem, dass das Formluar nicht mehr abgeschickt wird.
Nach dem Submit reloaded er einfach das Formular mit allen Werten und schreibt die Nachricht weder ins Log noch wird eine E-Mail versandt.

Auch ein Entfernen der Radios aus dem Master-Template bringt nichts. Ich weiß dummerweise nicht mehr genau, was ich geändert habe seit es vor dem Radio lief 🙁

Hat jemand eine Idee,w as ich verbockt haben könnte?
Anbei das TS und Template:

Das TS:

plugin.Tx_Formhandler.settings.predef.validation-ajax-validation {

debug = 1

	# This is the title of the predefined form shown in the dropdown box in the plugin options.
	name = Formhandler Validation with AJAX based Error Checks

	isErrorMarker {

	}

	# These wraps define how an error message looks like. The message itself is set in the lang file.

		}
	}				

	finishers {
