That v6.3-RTLM is unlocked via 36 trophies of ZS. But v6.4-RTLM is 37 trophies required to unlock it. If you bring 36 trophies into the v6.4. RTLM would be defined as a lock. endurance legends is also locked owing to the linkage between previous EK and RTLM. could be potentially relative with EL.

You need to achieve at least 37 trophies in ZS. then automatically unlock the EL. If you've updated to v6.4. that's ok. it works in new version. This could definitely be the clue. I had 38 trophies in ZS, had finished RTLM and unlocked EK before upgrade to 6.4 (but 0% in CSF) and EL was unlocked for me.
