How can you remove a single filter from a multiple select?

if ($data['zones'] ?? null) {
                        $zoneNames = Zone::whereIn('id', $data['zones'])->pluck('name', 'id')->toArray();
                        foreach ($zoneNames as $id => $name) {
                            $indicators[] = Indicator::make('Zona: ' . $name);
                        }
                    }

if ($data['zones'] ?? null) {
                        $zoneNames = Zone::whereIn('id', $data['zones'])->pluck('name', 'id')->toArray();
                        foreach ($zoneNames as $id => $name) {
                            $indicators[] = Indicator::make('Zona: ' . $name);
                        }
                    }
