Those long stems are only runners if each leaf set also has a set of roots that are attached to it. If it's just a long stem of leaves with no roots, cut the entire stem off and chuck it.
When glosso doesn't get enough light that's how it grows......vertically. And unless each leaf set also comes with a set of roots, it's drawing strength from the rest of the plants and shading them.
Look for runners with leaf sets with roots attached.....cut them off and then cut the pairs of leave sets apart. Each two-leaf set, with roots is one plant that can then be planted into the substrate. This will 'seed' your glosso bed.
Look carefully for the roots. Some may have roots and some may not. Once you see a string with them you will then see that the ones without them are worthless and counter-productive to propagating the bed.
