Poller package - pick one row from multiple rows

I have some wireless radios which have their software version split across two mibs (.1.3.6.1.2.1.47.1.1.1.1.10.1 and .1.3.6.1.2.1.47.1.1.1.1.10.4)

I have tried to configure a poller package for this to show the information on the node details page, but it pulls back 5 rows (4 of which are empty and 1 has the version). The different versions have these on different rows.

Is there a way to use a regex expression to filter out the blank 4 rows as the system only allows results with one row?

See below for what i tried but it still keeps the empty rows.

Thanks
