Try the RemoveWithValues filter on an attribute ("att_index") that
never has missing values apart from this empty row:
https://weka.sourceforge.io/doc.dev/weka/filters/unsupervised/instance/RemoveWithValues.html

In the Explorer, determine the smallest value for attribute
"att_index" to determine "smaller_than_lowest_value_for_att_index".

-C att_index
-S smaller_than_lowest_value_for_att_index
-M (to remove missing values)

Cheers, Peter

In the dataset editor, highlight the instance, right-click on it, and choose “Delete selected instance”.

Cheers,
