We’ve been able to replicate this – it seems to be related to files being opened before the CM engine is connected. So if you leave TS files open and then restart or shut down/start Eclipse, those file types will not display status correctly. This also goes for other types that you switch to before the CM engine is connected.
Can you try restarting with an HTML file active instead and wait for the CM engine to be fully connected before moving to other file types, does this make a difference?
Our team is investigating further as well and we will keep you posted – thank you for asking.
