Please explain your issue is in as much detail as possible.
When you get the event to refresh trade route from successful expedition, it does not refresh the modifier. Reason: modifier should be removed and added again. Compare:

# Refresh trade route sea
province_event = {
id = WoL.10131
...
hidden_tooltip = {
remove_province_modifier = trade_route
}
add_province_modifier = {
name = trade_route
duration = 10950
}
...
- sea route is working fine.

# Refresh trade route land
province_event = {
id = WoL.10130
...
add_province_modifier = {
name = trade_route
duration = 10950
}
- modifier is not removed so it just expires.

Steps to reproduce the issue.
Play a character with capital in:
OR = {
region = world_steppe
region = world_persia
}
Choose business focus.
Establish trade route. Look at the expiration date of modifier in your capital province.
Wait until event WoL.10129 fires.
Check expiration date again. It hasn't changed.
