Location: Import/Export locations not working as expected

[dazzzl]

Describe the bug
I moved form local-NLP-Backend and would like to import my old database. I wrote the following script:

#!/usr/bin/env python3

import csv
import sys


with open(sys.argv[1]) as incsv:
    with open(sys.argv[1].split(".")[0]+"wifi.csv","w") as wificsv:
              with open(sys.argv[1].split(".")[0]+"tower.csv","w") as towercsv:
                        inobj = csv.reader(incsv)
                        wifiobj = csv.writer(wificsv)
                        tobj = csv.writer(towercsv)
                        wifiobj.writerow(["mac","lat","lon","alt"])
                        tobj.writerow(["mcc","mnc","type","lac","cid","psc","lat","lon","alt"])
                        for row in inobj:
                            match row[1]:
                                case 'WLAN2':
                                    wifiobj.writerow([row[0].split("/")[1].replace(':',''),row[2],row[3],''])
                                case 'LTE' :
                                    rfid = row[0].split("/")
                                    tobj.writerow([rfid[1],rfid[2],'3',rfid[5],rfid[3],rfid[4],row[2],row[3],''])
                                case 'GSM':
                                    rfid = row[0].split("/")
                                    tobj.writerow([rfid[1],rfid[2],'1',rfid[4],rfid[3],'',row[2],row[3],''])
                                case 'WCDMA':
                                    rfid = row[0].split("/")
                                    tobj.writerow([rfid[1],rfid[2],'2',rfid[4],rfid[3],'',row[2],row[3],''])

the csv files was accepted and in the location database, the entries are there. However, if I export the cell or wifi locations, only some old locations are present. Also the network localization in areas which are in the local NLP database do not work.

To Reproduce
Steps to reproduce the behavior:

1. Import locations form the script
2. Export locations -> no new locations are there

Expected behavior
Imported entries should appear in the export

System
