@Ratslinger, thank you for your prompt input. Yes I did change the Control Properties and managed to get rid of the Label. However thee are still 1 issue remaining:
The hard copy print out is with a CROSS instead of a TICK mark as shown on screen, also the box is not 3D as shown on screen compared to the hard copy printout。
Note : I made the screenshot by using the Print To File feature. My system is Kubuntu 19.04 running the latest LO 6.3. I have some Windows PCs around for testing and will test and report back here.
In the meantime, I tried to a sample file here but was unable to. Can someone help me how to add an odt file here?
