Mifare DESFire Emulate UID not working

[Fabunator]

Describe the bug.

I have a copy of my woking place badge from Version 0.97.x
In this version i could emulate the UID and use this to log into my work.
In version 0.99.1 this is not possible any more.
I also made a new copy with the current version but nothing changed.

The type of the Tag is ISO14443-3A (Mifare DESFire EV1 4k) in the nfc file the type is Mifare DESFire

Reproduction

Hello @Fabunator !
I can't reproduce any problems with UID emulation. We need more information here. The protocol below Mifare Desfire is ISO14443-4A, not 3-A. The UID emulation for iso-3a and iso-4a are different.

1. Is it possible that your reader starts to read more than just UID? Does the emulation still works on 0.97 version?
2. Do you have any Logs during emulation? If readers reads more than just UID, you will see Log button on the screen during emulation. After pressing OK, you will have a screen with raw data received from reader. If you have this, please share this raw command here

I am sorry i made some mistakes in my description
The tag is of the Type ISO 14443-4 (Mifare DESFire EV1 4k)

I added 2 .nfc files from different Firmware Versions of the Flipper. (changed the UID for reasons)
The first one is from 0.93.0 the second from 0.99.1
In Version 0.93.0 the emulation of the UID works for both files and the reader can detect my badge
In Version 0.99.1 the reader is not detecting my emulated UID
