Difference from v3 - Blank merge fields appear as blank lines

[citobori]

I have a simple label created in glabels v3. The text is just:

${5}
${6}
${7}

In version 3, when performing a mail merge from a CSV, if the CSV field was blank then the line on the label would be skipped and the following line would be moved up to take its place. EG if ${5} was "blue", ${6} had a blank entry in the CSV file of "", ${7} was "yellow" then the label would appear in glabels 3 print preview as:

blue
yellow

in glabels 4 print preview it appears as:

blue

yellow

Is this a deliberate change or is there a way to change this behaviour? So blank entries are not shown as blank lines?

Thanks!

Look at the "n" modifier in the substitution field spec:

Thanks Jim, that helped sort out the issue. My label now looks like:

${5:n}${6:n}${7:n}

Blank lines now are suppressed just like in v3.

Thanks again, and keep up the good work with the glabels - it's a great tool!
