I spent a few minutes looking at this.  One issue I see is that I don't know where the independent variable name should go.  When I look at SPSS output for a model (for example, https://libguides ... /independentttest), I don't see it there either.

Take for example the following example:
The name of independent variable is nowhere in the table.
In writer, there is the syntax line that i can extract it. But here the info is missing.

Also, note that writers format odt are not opening at all. They are broken. Writer tries to fix them without luck.
