I have a Kindle Fire 10 tablet (7th generation) running Fire OS version 5.3.6.4 with the Bible app version 8.0.8 installed. I have a considerable number of highlights (maybe a couple hundred?) made in several resources on it over the course of the last week or so that I cannot get to show up on my desktop, which is running Windows 10 Pro version 10.0.17134 and has Logos 8 version 8.2.0.0015 installed. An example of one such resource I have made highlights in is:
LLS:NICOT01GE2
2012-01-30T17:54:41Z
NICOT01GE2.logos4
I made a highlight in this resource on the desktop this morning and was able to get it to appear in the resource on mobile tonight. I deleted that same highlight from mobile and it then disappeared on desktop as well, so at least some two-way syncing is in fact taking place. However, the highlights I have been making in this (or other resources) lately on mobile are not appearing on the desktop. The highlights I am having problem with are all the same kind -- they are "Yellow" under the "Solid Colors" palette.
I do not believe this is a case of simple user error, although I would be quite happy to be proven wrong. On the desktop I have the visual filters on the resource set to display all notes and highlights available (see screenshot below).

Although I am using this resource as an example, my problem is not limited to highlights made in just this resource on mobile. I am having the same issue with all resources on mobile that I have made highlights in during the past week or so. I have tried deleting the resources on mobile and re-downloading them, but this is not fixing the problem. I am afraid to uninstall and reinstall the app, because I do not want my highlights to be be deleted forever. Please advise!
