[MSFS24] Managed speed changes to an arbitrary value after creating a discontinuity

[ApocalypsePlease0]

During cruise phase, the FMC didn't program in the STAR correctly because it's supposed to enter a "MANUAL" fix after the last dedicated fix on the arrival, so I decided to add a random navaid (LAM in this case) and delete it so it adds a discontinuity between the last STAR navaid and the first navaid of the approach. It did so successfully, but it set my cruise managed speed to 243 IAS in the FPLN page, but the actual speed it went to was 220 IAS. I tried going direct to the next navaid in the sequence, but it didn't help and the speed stayed the same and I had to keep using the selected speed mode.
