I could not understand why I was seeing blacked (unread) topics on the forum but was receiving the (new) & (latest) counts on the header.
When I realised I could reset the settings to include all new instead of time limited I noticed that the (new) count went to 29 but there were more that 29 in the list.
It was not until I got below 29 that the count started to reduce, replicating the actual remaining topics on the forum.
Just thought I would share this - not that its a high priority. Prefer you to focus on solar panels and auto calibration
