what the others said
Pollinating at 5-6 in the evening is way too late IMHO to pollinate. If you have nocturnal daylilies then it may be ok but as was said the fluid has already dried up by 5 or 6 especially in the heat. I'm not sure what your temps are like right now but even if it's in the high 80s and your "feels like" is higher then it could cause things not to set. I have some daylilies this year that haven't set a thing and they usually set pods really well. I do find that for whatever reason pods set better on rebloom scapes for me, if they do set on first scapes they usually abort.
If you can try and pollinate early in the morning. When I was able to get to the garden before 7 am I would have my pollinating done by 8 am usually but no later than 9:30. What I would do is pollinate everything and then go back and tag the blooms. I use the same pollen for everything (different pollen but same pollen for all spiders, same pollen for all teeth, same pollen for all patterns, etc.) so it is easy for me to go back later and tag if I have other things to do.
And just keep in mind that not all pollen will be good even if it looks good and not all plants will set pods. Some plants may set a few while others set on every bloom and then some don't ever set pods.
