Question Why string from TextMeshProUGUI is not parsed into a number ?

I have no idea why it doesn't work


but it works


7 is 7, which is obtained from TextMeshProUGUI, which is written in code.

So why is the first 7 not a number, but the second 7 is a number?

 

using System;
using System.Collections;
using System.Collections.Generic;
using System.Text.RegularExpressions;
using TMPro;
using UnityEngine;

public class EffectMng : MonoBehaviour
{
public Shader shader;
public SpriteRenderer Effect;
public GameObject OnButton;
public GameObject OffButton;
public TextMeshProUGUI TextMesh;
public string CurrValue = "1";

void FixedUpdate()
{
float CF;
//string newCurrValue = TextMesh.GetParsedText();
//Regex.Replace(newCurrValue, @"\W+", "", RegexOptions.IgnoreCase);
string newCurrValue = "7";

if ((CurrValue != newCurrValue) & (Single.TryParse(newCurrValue, out CF)))
{
CurrValue = newCurrValue;
if (CF < 1f)
CF = 1f;
//Effect.material = new Material(shader);
Effect.material.SetFloat("_Radius", CF);
}

}
}
