Dear list,

As it turns out, my workaround here is subpar since it inserts an undesired 
line after the description block.

Hans was very kind to send me a fix to place in cont-new.mkxl that fixes the 
issue. However, due to my errors in properly pasting the fix correctly, it did 
not work. I updated LMTX today and the fix is already merged.

I am pasting below Hans' fix for reference (for anyone who might come across 
this later) –
