This is not reproducible in 7.3.x.

Steps to reproduce:

1. Create a new structure with a repeatable and localizable text field.
2. Add the template associated to the previous structure.
3. Add a new web content based on the text structure:
   1. Add a value ('hello') for the English translation.
   2. Change language to Spanish.
   3. Add a new text field and fill it with some content ('que tal').
4. Save the web content.
5. Edit the web content and swith between English and Spanish to see the values.

Expected result: 

• English: you can see one text field: 'hello'
• Spanish: you can see two text fields: 'hello' and 'que tal'

Current result:

• English: you can see one text field: 'hello'
• Spanish: you can see only one text field: 'que tal'

You can see in the content source that for Spanish translation:

• First field content is replaced by the second one instead of keeping its the default English value.
• Second field values are empty.

<?xml version="1.0"?>
<root available-locales="es_ES,en_US" default-locale="en_US" version="1.0">
 <dynamic-element index-type="keyword" instance-id="YHzF2RZH" name="Text69778719" type="text">
 <dynamic-content language-id="es_ES"><![CDATA[que tal]]></dynamic-content>
 <dynamic-content language-id="en_US"><![CDATA[hello]]></dynamic-content>
 </dynamic-element>
 <dynamic-element index-type="keyword" instance-id="qiqf9yqy" name="Text69778719" type="text">
 <dynamic-content language-id="es_ES"><![CDATA[]]></dynamic-content>
 <dynamic-content language-id="en_US"><![CDATA[]]></dynamic-content>
 </dynamic-element>
</root>

 And this is the (correct) source generated in 7.3.x for the same case:

<?xml version="1.0"?>
<root available-locales="es_ES,en_US" default-locale="en_US">
 <dynamic-element name="Text3ukl" type="text" index-type="keyword" instance-id="zhbf">
 <dynamic-content language-id="es_ES"><![CDATA[hello]]></dynamic-content>
 <dynamic-content language-id="en_US"><![CDATA[hello]]></dynamic-content>
 </dynamic-element>
 <dynamic-element name="Text3ukl" type="text" index-type="keyword" instance-id="rwpj">
 <dynamic-content language-id="es_ES"><![CDATA[que tal]]></dynamic-content>
 <dynamic-content language-id="en_US"><![CDATA[]]></dynamic-content>
 </dynamic-element>
</root>
