Nope, no reason not to use your Clear v2 cartridge as the results will be identical to Clear v4 and the materials will be mixable. Clear was a bit of a tricky case. As @kevinduhe mentioned, Clear V3 was discontinued but it did require different material settings and some users may still have cartridges. That’s the reason for the jump from Clear V2 to Clear V4.
