Issues with upgrading Skuid on Salesforce Summer '19 instances

Hi there,

Currently one of our clients wants to upgrade to 11.2.8 in their salesforce sandbox for testing purpose, however we got the same issue ’ You can’t remove design attributes ‘type,id,parameters,useURLParameters’ when the component implements a Lightning Page interface.
page: You can’t remove design attributes ‘type,id,parameters,useURLParameters’ when the component implements a Lightning Page interface’

Contact with Salesforce and they asked us to raise this issue to you. The org id is 00D5D00000090ga and the install link is https://test.salesforce.com/packaging/installPackage.apexp?newui=1&p0=04t4A000000AekB

Can you urgently fix this as our client is waiting for this for a while?
