To avoid this error, make sure that the "Location" does not overlap.

As seen in the screenshot below-

Specifications for LHS table margin are:

X axis- 2px and Y axis- 0px

Width- 392 and Height- 15

Specifications for RHS table margin are:

X axis- 393px and Y axis- 0px

Width- 391 and Height- 15

This has lead to location overlapping. 

To rectify this, we need to change the specifications of the RHS table margin as follows: 

Set X axis at 394px 

This should resolve the issue.
