Hi Christine,

That is because text objects were created with annotative text style and in model space you have scale (you can view and set current scale on the Status Bar) other than in viewport in layout.
You can look at this discussion:
https://forums.autodesk.com/t5/civil-3d-forum/annotative-text-moves-when-i-change-my-ps-scale/td-p/4...
where you can find short video about such case.
In short - you need to synchronize multi-scale text positions for all annotative text objects with ANNORESET command:
