New component types generated when scaling an instance of a DC under certain conditions

When I make an instance of the DC, and then either use the Scale tool or the DC options dialog to set the actual length of the board (LenX), a new component type is created automatically, as if I had given the “Make Unique” command.

This is the probably the reason you are getting automatic unique copies:

Components becoming unique by themselves

A copy of a dynamic component becomes unique if you apply its properties in a way that changes its internal structure, for instance if some of its parts are set to remain a constant size when the object is scaled.

Here is a quick test. First with the internal box not set to retain its dimensions and the second with setting the internal box dimensions to a fixed size.

So, in your case try making the wood board at the starting size before making it into a component rather than setting its starting size in the component attributes.
