ComponentDidUpdate firing multiple time instead of once per update

by

My component is performing calculation based on the result from before user performs a change, and afterwards, and for some reason, the component seems to be running the function multiple times instead of once per change, which is resulting in inaccurate results. Any suggestion on what could be causing the problem?

This is the code:

import * as React from 'react';
import { ILiquidiManagerProps } from './ILiquidiManagerProps';
import {AccountValue} from './AccountFields';
import {LiquidTEUR} from './DummyContent';

interface SubtotalState {
    Account?: any,
    SubtotalValue?: any,
    iteration?: number,
  }

export default class SubtotalValues extends React.Component<ILiquidiManagerProps, SubtotalState> {
    public constructor(props: ILiquidiManagerProps) {
        super(props);
        this.state = {
            Account: LiquidTEUR.Subcategories.find(item => item.Name == this.props.label),
            SubtotalValue: 0,
        }
    }
    
    private getText = data => {
        this.setState({SubtotalValue: data});
    }

    private initiateValue = () => {
        let Account = this.state.Account;
        let subtotal = 0;
        Account.Accounts.map((item) => {
            subtotal += item.Value;
        })
        this.setState({SubtotalValue: subtotal});
    }

    componentDidMount(){
        this.initiateValue();
    }

    componentDidUpdate(_prevProps, prevState){
        if (this.state.SubtotalValue !== prevState.SubtotalValue){
            let total = this.props.liquidTotal;
            if(this.props.label == 'Kreditlinien in TEUR'){
                total = total + prevState.SubtotalValue - this.state.SubtotalValue;
            } else {
                total = total - prevState.SubtotalValue + this.state.SubtotalValue;
            }
            this.props.getValue(total);
        }
    }

    public render(): React.ReactElement<ILiquidiManagerProps> {
        console.log(this.props.liquidTotal + "Subtotal");
        return(
            <React.Fragment>
            <a className="collapsible" href="#">
                <div 
                    className={`p-2 text-right value ` + this.props.bgColor + ` font-weight-bold ` + this.props.textColor}
                    data-date={this.props.date}
                    data-name={this.props.label}
                >{this.state.SubtotalValue.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".")}</div></a>
            <div className="content hidden">
                {this.state.Account.Accounts.map((item, key) => {
                    return <AccountValue key={key} label={item.Value} getValue={this.getText} subtotal={this.state.SubtotalValue} />;
                })}
                <span className="add-pos">&nbsp;</span>
            </div>
            </React.Fragment>
        );
    }
}
