Pitchers and SP/RP eligibility

Hey there … new to Ottoneu this year!!! … My appologies if this has already been addressed … but I was wondering why are SPs that were injured for all of 2025 and were SPs in 2024 and are coming back as an SP in 2026 are given an RP designation at the beginning of 2026? Pitchers that I have seen so far that fall into this category are Cole and Musgrove.
