Custom/default option is not present under execution tab

I have upgraded the katalon studio to 5.10.0 build:1
I was trying to add browser capabilities and notice there is no option of custom/default tab
Project → Settings → Execution → there is no custom or default tab.

As far as I can see, the functionalities previously available under Execution>Custom have been moved to Desired Capabilities (see the last line in the settings).

 [5.10.0]                 [5.8.7]

Thank you very much…!!!
