Can't find scroll locations

I have a very long page and there are a lot of Layout Blocks. I also have a fixed navigation header that the blocks float underneath when scrolling. I keep adding Scroll Locations and they disappear on me. I can’t find them anywhere even with the Show Overlays (Tab) enabled. I did notice that the one Scroll Location I could find, I tried to drag it to another location and it slipped “underneath” a Layout Block and disappeared. I can’t find them in Layers and even if the Layout blocks are moved to the back, the anchors are not visible. I tried to use the Layout Block anchor, but that doesn’t help much because I have a Nav Header that is pretty big and so the layer I’m trying to target is obscured by the Nav header. Anyone know what’s up with this?

p.s. I should note I’m a longtime Sitely (formerly Sparkle user) at least 10 years and have created dozens of complex sites with it. I love it and I am a huge fan. Best piece of software I own.

Unfortunately I can’t really help with this, but one possible workaround might be to temporarily lock or hide the Layout Blocks while placing the anchors.
