Upgrade to 4.2 from 4.1.3-1 - charts display issue in default sitemap BasicUI

Setup, Configuration and Use Items & Sitemaps

Hey, I’ve just upgraded to 4.2 from 4.1.3-1 (in rPI installed with apt) and been using BasicUI for ever.
I have a chart displaying a temperature defined like that:
Chart item=WeatherCompanyObservations_CurrentTemperature period=D refresh=900
the result of it was that when I opened the sitemap I had immediately a chart visible where expected. After the upgrade behavior is somewhat not intuitive. Place where chart was present is empty (as below)

but then if I click on this empty space, I’m getting this:

and then need to click on refresh to get the chart

Is there a way to display it without these manual steps with some default period as before?

Please ignore my ask. Behavior came back to ‘normal’ by itself about 1h after the upgrade, haven’t touched anything.
