Layer effects not saving when merging - 24.3.0

I am finding that when I try to merge a layer which has effects with another layer, PS deletes the effects of the layer.

Hi @April26600948ulqm looking at your two compares the original layer has a vivid light blend mode and when you merged it now has normal. What happens if you change it back to Vivid Light?

......It goes blank. This isn't what I want. The vivid light and effects are on the "What's around town", so both the layer effects and blend mode dissapear when I try to "merge layers" with the background layer under it.
