[TYPO3-english] spamProtectEmailAddresses not working

[ondro]

Hello

I extend page properties and add new field "submenu_text" which is RTE input.
I render it via fluid cObject from typoscript lib as follow:

lib.project.submenuText = TEXT
lib.project.submenuText {
	data = levelfield : -1 , submenu_text, slide
	stdWrap.parseFunc < lib.parseFunc_RTE
	stdWrap.wrap = <div class="menu-text">|</div>
	stdWrap.required = 1
}

All is correct html is rendered but when typolink type email is used in rte email link is not encrypted on FE

in ts I'm using following config:

config {
        spamProtectEmailAddresses = 2
	spamProtectEmailAddresses_atSubst = <span>@</span>
}

Why is email not encrypted?
