Caption showed in master document is different from the sub-documents

Hi, as the title says, I have a problem with how the captions in my sub-documents are shown differently in the master document. I use the options “Numbering Caption by Chapter” level 1 in my sub-documents for tables and illustrations and they work just fine. However, when I view the file from the master documents, all of the captions now are only showed as level 0. So, please kindly help me fix it. How can i change it back to level 1 in the master document?
