Export Layers to File with Artboards

Hello,

I have a question about exporting with artboards. I've become very familiar with using artboards in Photoshop over the last few years and I love the workflow, but it seems like some functionality is still missing or misbehaving.

I have two artboards set up  with a few layers on each. (I am exporting a series of merch items into PNGs, one artboard has men's products and one has women's) I'd like to be able to batch-export these layers into their own PNG files. "Export artboard to files" is my go-to export option and works perfectly for multiple artboards with a one-image export. "Export layers to files" is more old-school, but seems like the right choice. There are even options for Trimming the layers --Great! But when I export, the layers are not trimmed and I have to re-import them all into photoshop and batch them out without artboards for it to work.

Is there a step that I'm missing, or is this just broken?

(Maybe my issue is that I'm using Photoshop CC2018 19.1.7 — not sure if this is corrected in CC2019, but I have not upgraded yet for two reasons: new versions are often fairly buggy and this version in particular requires an OS upgrade as well )

I can use a work-around in the meantime, but it takes much longer to do this manually and I'll need to do this for many items. Below is my screenshots of the artboard

set-up and the resulting export.

Any help to speed up this process would be appreciated! Thank you!
