delete hasAddress did not delete the address

[naturzukunft]

1. i created a new pod
2. and add two adresses:

@prefix : <#>.
@prefix solid: <http://www.w3.org/ns/solid/terms#>.
@prefix foaf: <http://xmlns.com/foaf/0.1/>.
@prefix pim: <http://www.w3.org/ns/pim/space#>.
@prefix schema: <http://schema.org/>.
@prefix ldp: <http://www.w3.org/ns/ldp#>.
@prefix pro: <./>.
@prefix n: <http://www.w3.org/2006/vcard/ns#>.
@prefix inbox: </inbox/>.
@prefix xyz: </>.

pro:card a foaf:PersonalProfileDocument; foaf:maker :me; foaf:primaryTopic :me.

:id1606159246101 n:street-address "street".

:id1606159272029
n:postal-code "1244"; n:region "myregion"; n:street-address "street2".
:me
    a schema:Person, foaf:Person;
    n:fn "xyz";
    n:hasAddress :id1606159246101, :id1606159272029;
    ldp:inbox inbox:;
    pim:preferencesFile </settings/prefs.ttl>;
    pim:storage xyz:;
    solid:account xyz:;
    solid:privateTypeIndex </settings/privateTypeIndex.ttl>;
    solid:publicTypeIndex </settings/publicTypeIndex.ttl>;
    foaf:name "xyz".

3. Clicked on the red minus symbol below the address in the profile editor Label: "Remove this has Address". That results in:

@prefix : <#>.
@prefix solid: <http://www.w3.org/ns/solid/terms#>.
@prefix foaf: <http://xmlns.com/foaf/0.1/>.
@prefix pim: <http://www.w3.org/ns/pim/space#>.
@prefix schema: <http://schema.org/>.
@prefix ldp: <http://www.w3.org/ns/ldp#>.
@prefix pro: <./>.
@prefix n: <http://www.w3.org/2006/vcard/ns#>.
@prefix inbox: </inbox/>.
@prefix xyz: </>.

    solid:privateTypeIndex </settings/privateTypeIndex.ttl>;
    solid:publicTypeIndex </settings/publicTypeIndex.ttl>;
    foaf:name "xyz".

4. hasAddress reference was deleted, but the address is still there.
   That is what the red minus tells me, but the pod will get messy after a time. I cannot find a way to delete the address id1606159246101
