Locus Map 4 update geocaching list of many caches

Hello, I have a pocket query with cca 750 geo caches. When I update them all, the Locus 4 always finished it with error status everytime. The network is not an issue, because I sit next to router, also in Locus Classic I can update the same list without problems. So I have to filter for example half of them (by example traditionals and then mystery caches). When the list is smaller, everything is ok. In Locus Classic there is no problem to update list of > 5000 geo caches. Also the update of the list of geocaches takes longer time. The limit of Geocaching is refresh 16000 caches a day (by Groundspeak) - API limit. I have a list of geocaches within 80km radius from home and I need refresh them all because some of them are disabled/archived. I usually refresh the whole list (around 10k geocaches) every three days.
