By default, when replicating tables the 'Check Out' for the table is set to Schema Only rather than 'All Records'. You will need to go into the advanced options when creating the replica (screen1.png). Then you can set the 'Check Out' to 'All Records' (screen2.png).
This is by design.
Please have a look at the below link for more details:
[ NIM040283 - Using GP tool (create replica) to create replica and set ALL_ROWS for expand feature classes and tables, the attribute table only has its schema replicated.]
You can also have a look at the below post for a good workaround:

Hope this helps!
