Unable to store updates to chart layout

I have an Amibroker 6.20.1 that I have been using for a while without any problems. Now for some reason it does not store any updates to chart layout. If I create a new pane in a window and then do a “save all” it doesn’t show up when the app is shutdown and restarted. Same thing happens with new chart windows. If I create a new chart window and save it then it doesn’t show up on the restart of app. All updates to formula are stored without any issue and everything else works fine as well. Just that I can update the charts.

Does anybody know how to address this issue? I am running this on Win 8.1 Pro.

Check Tools->Preferences->Miscellaneous Auto Save layout on exit
