The family is not properly constrained 

In the family ... Go to visibility graphics >>> annotation tab >> enable all >> then try to flex the length of the truss.

If your intent is to make it parametric for all projects, you need to add more reference planes, reference lines...These are elements you can lock and constrain the chords and web elements to. Same like any other family

 

 

If you want to use it just for 1 project...ie: 1 size non-parametric in terms of Lenght and hieght(s), you can do the following

  1. In the project section view sketch Change to hidden
  2. Trace the wireframe of the Truss by place detail lines 
  3. Isolate the detail line and place the web as detail lines
  4. ... copy that to clipboard and paste it in the truss 
  5. Place Chord and web elements using Pick line
  6. Delete the detail lines you pasted and load truss to the project

You need to learn the principles of Revit Family modeling then do some more practice...I do not believe it is something one can learn in a forum post. Can only give you tips to follow

  1. Start by placing the top cord and lock the ends of the Chord lines to the intersections of the refernce planes.
  2. Next move to the web members and start placing all which are in one direction (Ascending from left to right) and lock their ends as well
  3. Next do the web members of the other directions (The ones ascending from Right to Left) - these will lock automatically to the ends of the previous one
  4. Now place the bottom chord and constrain to plain ...ends will lock to the top chords which you already placed
  5. Flex and Check 

 

Attached is your family Constrained to function (It is version 2022 though I don't have 2020 in this office - You will need to open it and see how it is built and constrained)..It is not how I would design the web but that's how it looked in the image you posted (Original Post) ... See below GIFF how it functions

 

Control Parameters:

  1. First Click and Second Click determine the length
  2. The Height of the Truss, Height of Middle Chord and Length of the transition you input in properties palette
  3. Added an offset from both ends which you can set to Zero if not needed
