In the "select tables to replicate" step, the user is asked to select the tables by either clicking on the checkboxs or by using the "select all" checkbox.
The select all checkbox seems to work globally even when only subset of tables are displayed.
Step to reproduce:
Search for a subset of tables, by inputting a query into the search box. After the query results are displayed, select the "select all" checkbox.
The table selected counter will display that all the tables in the databse are selected.
