FWIW it is unlikely that a 7.3mm wide chain will work much better than a 7.1mm wide chain. There are most certainly circumstances where a 7.3mm chain wouldn't work, but that is a different matter.

I was wondering if it wasn't the chain width, but that the first new chain was stiff or twisted which was causing the problems when shifting. I did liberally lubricate the chain with oil, but that didn't stop the problems when shifting.

Hi,
That sedis / sram (marked) chain with flat side plates is 7.4 mm IIRC.
There are no other markings so no idea what model.

https://en.wikipedia.org/wiki/Bicycle_chain
"6 speed – 7.8 mm (5⁄16 in) (all brands)
7 speed – 7.3 mm (9⁄32 in) (all brands)
8 speed – 7.1 mm (9⁄32 in) (all brands)
9 speed – 6.6 to 6.8 mm (1⁄4 to 9⁄32 in) (all brands)
10 speed – 6.2 mm (1⁄4 in) (Shimano, Campagnolo)
10 speed (Narrow) – 5.88 mm (7⁄32 in) (Campagnolo, KMC)
10 speed (Narrow, Direction) – 5.88 mm (7⁄32 in) (Shimano CN-5700,CN-6700,CN-7900)
11 speed – 5.5 mm (7⁄32 in) (Campagnolo, KMC, Shimano CN-9000)"
