Assets Deleted

Is there a known issue about images/assets being deleted when you update any given region?

It happens only with the images I have in one specific bucket. I add images, save and everything is ok, but as soon as I edit that region, they will disapear (they still in the bucket but the won't show up in the frontend). Can you help me please? This is the code I have in my template:

Forgot to mention, it only happens in the live site, I tested in the local site and all works fine.

<div id="photos">
                    <perch:before>
                        <ul id="gallery" class="imagelisting glist">
                    </perch:before>
                        <perch:repeater id="image" label="Photos" max="12">
                            <li class="item">
                                <a href="<perch:content type="image" id="image" label="Image" width="1000" bucket="directorio" />">
                                    <img src="<perch:content type="image" id="image" label="Image" width="300" height="300" crop="true" quality="75" />" alt="<perch:content id="alttxt" type="text" label="Alt text" />" width="<perch:content id="image" type="image" label="Image" output="w" />" height="<perch:content id="image" type="image" label="Image" output="h" />" />
                                </a>
                            </li>
                        </perch:repeater>
                    <perch:after>
                            <li class="gap"></li>
                            <li class="gap"></li>
                        </ul>
                    </perch:after>
                </div><!-- #photos -->
