Not able to open a Mac OS Extended (Journaled) SSD disk in Boot Camp
Disk 1 looks like a typical, bootable OS X drive with an EFI-partition (200 MiB), a main OS X volume and a Recovery HD partition (620 MiB).
I can't say it for sure, but I'd assume your external SSD (disk1 in the Disk Management screenshot) contains a CoreStorage Logical Volume Group on the second partition (112.20 GiB).
To check if the second partition of your external disk contains a CoreStorage LVG boot to an OS X volume and enter diskutil list or diskutil cs list. If you detect the volume type Apple_CoreStorage next to the second partition of your external drive after entering the first command or a CoreStorage Logical Volume Group or a Logical Volume with the size of ~120 GB after entering the second command, your external disk contains a CoreStorage volume.
A Paragon knowledge base article states that Paragon HFS+ isn't compatible with CoreStorage:

...
[HFS+ for Windows]
If you are running HFS+ for Windows in a Bootcamp configuration, you won’t be able to see Mac OS X partition due to Core Storage restrictions. If you can disable Core Storage as described above, this will give you access to Mac OS X system drive from Bootcamp.

To enable r/w support you have to revert the CoreStorage LVG to a normal HFS+ volume.
To revert a CoreStorage volume boot to a Recovery HD or the OS X volume on your internal disk. Enter diskutil cs list and copy the Logical Volume UUID. Then enter: diskutil cs revert LVUUID. Some CoreStorage LVs aren't revertible. If you have enabled FileVault on the external main volume you have to use a passphrase: diskutil cs revert LVUUID -passphrase [passphrase].
