Hello!

First of all, thanks for this great software.
I use Outlook CalDav Synchronizer to sync my calendars between multiple devices.

Recently, I started using the color mapping feature for mapping Outlook category color to COLOR attribute.
On my PC it seems to work correctly, but on my notebook, where the data file with the calendars is not the default data file, the mapping does not work because the categories from the default one are used instead.

The fallback categories with the HTML color name are created in the default account and added to the event although the mappable category would exist in the data file of the calendar:

Also the EventColorToCategoryMappings are created in the options.xml, which is not the case on my PC. Are they only created if there is no matching category and a fallback category is created?

<MapEventColorToCategory>true</MapEventColorToCategory>
<EventColorToCategoryMappings>
	<ColorCategoryMapping>
	  <HtmlColor>lightsteelblue</HtmlColor>
	  <PreferredCategory>lightsteelblue</PreferredCategory>
	</ColorCategoryMapping>
	<ColorCategoryMapping>
	  <HtmlColor>peachpuff</HtmlColor>
	  <PreferredCategory>peachpuff</PreferredCategory>
	</ColorCategoryMapping>
</EventColorToCategoryMappings>

Another issue:

If I create an event on my notebook, I myself am added as attendee (see below). I am not sure if that is also because of the default data file issue, but it does not happen on my PC.

Event created on my PC:
