CBLCNVRT is not a 100% tool . Just check the mod log of the tool ( it will be present in your mainframe system library , most probably SYS*.**.CAIMAC) and you will get a rough idea about it's limitations .
In our project we have developed a new tool using REXX which converts COBOL layout to EZT Macro layout and have tried to overcome some of the problems in CBLCNVRT. The tools also makes the layout as per the coding standards and best practices of your project . I think you might also start creating a similar tool in your project.
