iOS: position log only shows one entry, no node history or route lines on node map

Over the past year or so I have noticed that the position log for my node sometimes contains many entries (history), and sometimes only contains a single entry that gets overwritten each time a position update occurs. It seems that without multiple entries in the position log I cannot show node history or route lines for my own node on the node map.

My device metrics and environmental metric logs keep their histories. The position logs of other people’s nodes show history / multiple entries. How do I ensure my own position log keeps a history? There must be a setting I am overlooking.

Node: RAK 4631, 2.5.5
App: 2.5.9 (1288)
