Specialized Power Systems is installed but does not show up in Library Browser (R2025b Update 2)

I'm trying to use the SPS blocks in a model, but when I search the names, or look them up in the Library Browser, they don't show up.

I know it's installed in my PC, because I can access the library iself through the 'sps_lib' command. I am aware of the fact that it's being discontinued, and was not included in the base version of R2025b; but I already have the updates to restore it, so I presume it should be able to show up as normal.

I can even copy and paste the blocks from the library's file and run a simulation, though that's awfully inconvenient.

Is there a way to make the library show up again in the browser and in the search without having to reinstall anything? And if it being "hidden" is the intended behaviour, is there anything that can be done?

The SPS library is planned for removal in R2026a (Release Notes for Simscape Electrical). To make the transition smoother, I would suggest exploring the spsConversionAssistant command, which can help convert existing models to Simscape Electrical (Upgrade Specialized Power System Models to use Simscape Electrical Blocks - MATLAB & Simulink). For now, Update 2 has reintroduced the SPS library as a temporary solution; however, it remains hidden from the Library Browser and cannot be made visible through standard settings. If you rely on these blocks frequently, it might be a good time to start planning the migration process while using the current workaround for immediate needs.

It was Update 1 that reintroduced SPS library. You can see it if you give the command sps_lib
