It looks like you do NOT have a RODI! It looks like just a CARBON and
SEDIMENT filter???!!!
Since the canisters are labeled, I would expect to see something that would
say RO (or membrane- Not SEDIMENT) and DI would be listed as DI or DE-ION or
something...

I would check with the manufacture to validate what you do have!!

Sounds like there is no DI,, just a 3 stage, (pre, carbon and a
membrane.)
DI
will remove silicates tha RO leaves behind. Diatoms fed on silicates.
A DI add on can be purchased for about $50

The filters say on the out side CARBON 1 CARBON 2 and SENTIMENT so
replacing the filters should do the trick?
