Default themes update broken

[zerefgg]

Hello,
I've noticed that, we can not update the default themes from the ACP.
for example theme persona's latest version is 10.1.16
but on the ACP it shows Installed 9.1.38 | Latest 9.1.38 also for theme Lavender and Slick.

I managed to install theme persona v10.1.16 but It's broken.

Thank you!
