[BUG] For fossil_fuel_percentage the secondary_info does not show the result from template anymore after update.

[bjiirn]

Describe the bug
For fossil_fuel_percentage the secondary_info does not show the result from template.
This worked fine in v0.1.8.1. After updating to v0.2.2 this is not longer the case.
Instead the entity data is now shown.

To Reproduce
Steps to reproduce the behavior:

 type: custom:power-flow-card-plus
 title: Energieverteilung
 entities:
   grid:
     entity:
       consumption: sensor.power_from_grid
       production: sensor.power_to_grid
   fossil_fuel_percentage:
     entity: sensor.electricity_maps_anteil_fossiler_brennstoffe_im_netz
     name: Grün (DE Netz)
     secondary_info:
       entity: sensor.electricity_maps_anteil_fossiler_brennstoffe_im_netz
       unit_of_measurement: '%'
       decimals: 1
       template: >-
         {{ ((100 -
         states('sensor.electricity_maps_anteil_fossiler_brennstoffe_im_netz') |
         float) | round(1) | string + ' %') }}
   home:
     entity: sensor.power_house

Expected behavior

• I understand that this is a channel for reporting bugs, not a support forum (If you need help configuring the card, go to: Discussions).

• I have the latest version of the card installed.

• I have cleared my browser cache after installing, updating and configuring the card.

• The issue is not related to the UI-Editor not being rendered: "s.entries is not a function". This is a known bug, and is caused by Card Mod. Check the warning this readme section for more information on how to fix it.

I think i found the problem.
There seems to be a typo in the 'power-flow-card-plus-config.ts':

However i do not know how to generate the 'power-flow-card-plus.js' from the source so i cant test it.
Edit: Added a PR for this: #635

Update: I did now manage to compile the Code and it does not fix the issue.
I did not find what causes the problem jet, but i have a hard time understanding whats happening since im not that familiar with JavaScript.
I will try to find the Problem again when i have more time.
