unable to replace placeholder on recurring invoice

Hi,

I have been testing my custom Invoice template and for a single invoice, all field show exactly as required. After creating a recurring invoice, I received the following message:

The invoice for Testklant has been created and it's saved as a draft in your Zoho Invoice account. However, some of the placeholders used on your invoice template were not replaced with the appropriate information. Please check this before you send the invoice to your customer.

The placeholders which were not replaced are listed below:

%CustomLabel2%
%CustomLabel1%

These two custom fields are:

- the word "dagen" which is placed behind %payment terms%

- euro sign to be placed directly before every amount

I have added a screenshot of my invoice template with the place highlighted. Could you tell me why the placeholders are not used on the recurring invoice?
