Dynamic Title

Hi,
I have a project I am working on and to visualise its effect I want to use Power BI. There are 8 activities in the project, and each of the activities' impact is measured in $ as well. resulting in 16 attributes in total. In one Power BI window I want to visualise only the activities themselves, not its impact measured in $, so only 8 of the 16 attributes. 

I have used this code as of now: 

With this code, if I select for example Durban, T. Safety initatives and T. Activity, the title of the graph looks like this, exactly as I want it:

The problem, however, is when i have selected no location and no activity. Then the title looks like below, because I have filtered out the attributes in $:

I want the title to say "All Ports, All activities" when no location or activity is selected, but it seems like that does not happen because I have filtered some of the attributes out. 

I will add a link to a Google Drive file with a sample of the data as well:

If anyone could provide some guidance for how I could achieve that, it would be greatly appreciated. Thanks!
