After performing design calcs for an element, a green tick mark means everything is aok. A yellow tick mark usually appears with warnings and no tick when structural capacity is inadequate. Question is what are the structural implications of the design with the yellow tick? does it mean it can be used but one should be aware of the warnings or does one continue tweaking the design until a green tick mark is achieved? Just curious!!

Depends on what your local code stipulates and level of risk if something collapses.
Assuming that you refer to the steel design - red means you exceeded the safety ratio limit ; yellow you exceeded the slenderness limit but you are below the safety ratio limit.

There were some messages (errors/warnings) displayed during calculations of reinforcement.
Yes there were. I was wondering why the program does not provide the necessary reinforcement/stirrup arrangements in the design process to cover crackwidth/stirrup spacing/necessary reinforcement to satisfy seismic codes eg. EC8
It tried but for some reason was not able to. Could you send the rtd file and indicate which beam/column to look at?
Try the following:
1. Open the model with results
2. Select a small part of the model around the beam or the column you want to design and save it as a substructure (Geometry > Structure > save as substructure).
3. Export the element to the RC Design module and calculate reinforcement
4. Save the file and send it indicating which beam or column should be investigated.
If the file after compression is still to big select only the beam or the column in point 2.
POST EDITED (Change of information) !
After more detailed analysis of the reported situation I decided to edit this message and replace the original answer with the updated one.
The errors are displayed for beams with 'free ends' (no supports at span ends) as well as 'free' ends of cantilevers and have the same cause. Currently such 'free' ends are for some verifications treated in the same way as if there were supports there which results in unnecessary check of the provisions that should not be checked at all. This may result in having he following errors displayed:
Stirrup spacing is incorrect according to the seismic requirements (EN 1998-1:2004, 5.4.3.1.2 (6)P b )
The position of transversal reinforcement is incorrect according to seismic requirements ( EN 1998-1:2004, 5.4.3.1.2 (6)P )
Reinforcement percentage below allowable values due to the seismic requirements
Corrected in RSA 2017.
