Short answer. Article 2245 says credits not falling under the preferred categories enjoy no preference at all. Because none of these creditors outranks another, they stand on equal footing and share proportionately in whatever remains once the truly preferred credits have been paid.
What the law says
Credits of any other kind or class, or by any other right or title not comprised in the four preceding articles, shall enjoy no preference.

What "no preference" actually means
Article 2245 is a catch-all provision covering credits that do not fall within the specific preferred categories the surrounding articles establish. It states plainly that these credits "shall enjoy no preference." This does not mean the credits are invalid or unenforceable — it means that, relative to each other, none of them ranks above another. No creditor in this group can claim a superior right to be paid ahead of the others in this same category.
Why equal footing among these creditors implies proportional sharing
Once the debtor's assets have satisfied whatever credits truly qualify for preference under the surrounding provisions, what typically remains is distributed among the creditors who have no such preference. Because none of them has priority over the others, and the remaining assets may well be insufficient to pay everyone in full, the natural consequence of having no preference among a group of creditors is that they share the available remainder in proportion to their respective credits, rather than being paid in an arbitrary order that would effectively give one an advantage the article denies them.
This provision only governs ranking, not the amount owed
Article 2245 addresses priority among creditors when a debtor's assets are not enough to satisfy everyone, not whether a particular debt exists or how large it is. Each unpreferred creditor still has to establish the validity and amount of their own claim independently; what this article tells you is only that, once validated, none of these claims is entitled to jump ahead of the others simply because of some special right or title the more specific preference rules do not recognize.
What this means for creditors in your situation
If you are among several creditors with no special preference, your practical position is that you compete on the same level as the others in your category for whatever assets remain after preferred credits are satisfied. Understanding the total pool of unpreferred creditors and the total remaining assets is essential to knowing what proportional share you can realistically expect, since your recovery depends on how that remainder is divided among everyone standing in the same unpreferred position.
