I looks a lot like the leaf streak on daylilies. I suggest you take a good look at the base of your leaves to see if you see any soft of mushy spots. I would remove the infected leaves and perhaps even dig the bulb after they dry back to examine for borers in the bulb. https://hort.extension.wisc.edu/articles/daylily-leaf-streak/ There also is this possibility but less likely: https://www.gardeningknowhow.com/ornamental/bulbs/allium/allium-leaf-miner-control.htm
