Activity Stream appears cutoff; activity tiles are missing; console error Uncaught Error: [ng:btstrpd] App Already Bootstrapped with this Element


Some activity streams display cutoff where not all the tiles are displayed like shown here.  Notice the number next to 'Activities:' .  There is only 1 partial activity tiles in the Activity Stream

Release or Environment



The cause could may be a variable of type UI Page that appears on the Variable Editor of the form layout.  You will notice that if you remove the Variable Editor from the form layout, the issue is not reproducible.  If the UI Page called from the variable has custom code, it could interfere with the angular processing. 


Since this is a customization issue, we can only suggest using an OOB UI Page instead, or contacting the original author of the custom UI Page.
