Got two fingerprint letters

[Jerryl]

I got two fingerprint notice separately. One is from Service center (Dallas) and the FP was done on Oct 12. Today I got another FP letter from district office (San Antonio) and schedule to appear Nov 05.
However both letter says that I can discard the FP notice letter if the fingerprint was done in the reccent 90 days.
Anyone has the similar experience? Should I ignore the second FP letter.

Thanks

I received tons of fingerprinting letters.
Just follow the most official, or just go to all appointments.
