This message occurs during diary generation if one of your mini-calendar options contains both native combined dates and the use of one of the 2 formatting accumulation override options, namely Ignore All Other Options or Reset All Options.

These settings can interfere with the generation of combined dates and you should instead override the default sequence in which mini-calendar dates are formatted and make sure that all desired formatting options are set (for example, do not assume that the shade of the @ marker is 100%; if it needs to be 100%, then set it specifically).
