Erased both partitions of my hard drive and want to merge them. They show up as two different disks so I cant choose the partition option

Question

External hard drive partitions showing as 2 different disks, can't merge or repartition. I have erased both and want to merge into one.

EDIT: I have Reformatted both partitions to Mac OS Extended (Journaled) but still have the same problem.

macOS Mojave Version 10.14.4

Yes, when I do that they both show under the same physical drive. I was able to choose the parent drive after clicking "Show all devices" and then doing a master boot record. Thanks! — Eva, Commented May 1, 2019 at 14:13
Great, I have added it as an answer, if you could accept that all will be right in the world of AskDifferent guidelines! ;-) — Steve Chambers, Commented May 1, 2019 at 17:47

In Disk Utility go to the View menu and select

"Show all devices."

That should then show those two partitions under the "parent" physical drive mand allow you to repartition.
