Exception thrown when ensuring an XPathOrCssTarget has some value

Hi,
I have a plain XPathOrCssTarget

public static final Target LIBELLE_COMPETENCE_NUMERO = XPathOrCssTarget
        .the("libellé de la compétence numéro {0}")
        .locatedBy("#competence-clef li:nth-child({0}) .media-body > span > span");

then I use it (in a loop) to remember values

for (int i =0 ; i < CandidatForm.LIBELLE_COMPETENCE.resolveAllFor(actor).size() ; i++) {
    actor.remember("compétence" + i, CandidatForm.LIBELLE_COMPETENCE_NUMERO.of(String.valueOf(i+1)));
}

and then I ensure the same field later has the same value as stored

        for (int i =0 ; i < (int) actor.recall("nb compétences clé") ; i++) {
            actor.attemptsTo(
                Ensure.that(CandidatForm.LIBELLE_COMPETENCE_NUMERO.of(String.valueOf(i+1)))
                    .hasValue(actor.recall("compétence" + i))
            );
        }

but I get the following exception

[ERROR]   class net.serenitybdd.screenplay.targets.XPathOrCssTarget cannot be cast to class java.lang.String (net.serenitybdd.screenplay.targets.XPathOrCssTarget is in unnamed module of loader 'app'; java.lang.String is in module java.base of loader 'bootstrap')

Did I get something wrong or is this a bug ?
I have penty of Ensures on plain Targets (Target.the("").located(By.something("somethingelse")) having values and recalls and it works fine.
