Having some issue with Thrust Limit page

[PierreFSX 5]

I am trying to setup the Thrust Limit in the CDU (777) for a flight from Ottawa to Memphis. When I put the number 58 for 58C and hit LSK 1L the number is displayed for a fraction of a second and then the entry becomes blank. But the D- to N1 value is display. If I go to the takeoff page and add the required info, the Thrust info is missing and I cannot get the Takeoff speeds to work.

I must be doing something wrong? Or I am missing a piece of info.

I am using Prepar3d v4

Are the ADIRUs on and aligned? Selected departure runway? Is 58C a calculated value using a tool such as TOPCAT, perhaps it results in a v speed limit?

Yes the ADIRUs is on and aligned, I have also selected the departure runway and I have try 36C , the value was calculated by TOPCAT and it did the same thing.

I'd like to help but I'm not watching over your shoulder.  Give me enough to try to reproduce.  I need fuel, zfw, weather, runway, location etc., enough so I can start P3D and try the same exact situation.  Is 36C a runway or a derate?

I did found my problem, error in  the payload data and I think the runway was to short. Thanks you did help me by questioning the data input in the CDU.

If the runway is too short it should refuse to give you v-speeds, this is accurate. If your PC is a little slow or is at max CPU usage I guess it might be possible that it flickers the speeds or thrust settings for a moment as it computes and checks against the database.
