Yes it should be like this:

<wpml-config>
	<admin-texts>
        <key name="redux">
            <key name="thinkup_homepage_sliderpreset">
                <key name="slide_description" />
                <key name="slide_url" />
	    </key>
        </key>
    </admin-texts>
</wpml-config>

Did you fill these fields in your theme options?
Is it in Theme options > Homepage > Homepage Slider > Built-In Slider ...? or where ?
