You are restricting listings to the Balearic Islands only, but you have 3 regions: Illes Balears, Islas Baleares and Balearic Islands.
Your map is in Spanish now, so the only correct one is Illes Balears (i think).

You will have to edit all your locations so they are all in the same region.

With just GD installed, your users can change their password if you change the following setting:
GD > General > General tab > Allow user to see wp-admin area > YES

There is nothing I can do until I can log in, see image:

I am in Australia and Paolo is in Mexico. Please let us know when we can access your admin area. Thanks.

You can use the translation file, see https://wpgeodirectory.com/docs/translate-core/
or go to GD > design > search > SEARCH FORM DEFAULT TEXT SETTINGS

To review the review tab from the detail page: GD > design > detail > Exclude selected tabs from detail page > Reviews

To remove stars, add this to your CSS:

.geodir-rating {
    display: none;
}
