@djrogers2416, thanks for reporting. Please try if the issue does occur also using a new QGIS user profile. If it does, please provide a sample layer using which the issue occurs.

Hi Thanks for the reply. On a new user profile it works fine, I can only presume that one of the plugins is causing the issue on my main profile. Kind regards Dave Rogers

@djrogers2416, thank you very much for checking and replying. It would be very useful if you inform us when you find the offending plugin.
