plasma-nm applet 5.7.4 shows available WiFi networks around, after that if I try to connect some of them - plasma-nm applet doesn't show established connection (but connects to WiFi network successfully and network works well), but plasma-nm applet shows this connection in the list of available connections (not in the list of already connected networks), and even allows to connect to WiFi network already connected! In  	plasma-nm editor this network lists twice. Sometimes the bug is shown else: plasma-nm applet shows the connected network, but not all necessary information in the Detailes tab: for example, dont't show the IP address of connected network

Reproducible: Sometimes

Steps to Reproduce:
1. connect to any WiFi network via plasma-nm applet
2.
3.
